New in TreeSize Professional 9.1.2 Build 1873 (Feb 23, 2024)

New in TreeSize Professional 9.1.0 Build 1866 (Jan 18, 2024)

New Features:
In the details list and search results, it is now easier to select the relevant columns from all available options. The display is grouped by type.
When selecting a scan destination, you can now more accurately select your desired destination and configure access credentials.
File Search: Simple Search now allows you to use parentheses in your search term to refine your search. For example, entering (readme, license) *.txt will find all text files with "readme" or "license" in the name.
File Search: In Simple Search, spaces now act as AND links between search terms, not as part of the term. The search term "New Folder" now finds folders named "New Folder" as well as "Folder New" or "New Test Folder". Use quotation marks for exact matches. A comma now works as an OR operator; it is sufficient if one of the terms occurs in the name.
You can now start mass renaming directly from the Explorer context menu for selected files in Windows 11.
Via the jumplist entries in the Windows taskbar (the jumplist appears after right-clicking an application icon), various areas of TreeSize can now be opened directly, e.g. the most recently performed searches or scans.
File Search: File operations can now be performed directly on files inside zip files.
The details list now supports two additional columns, which can be activated via "More Columns" in the right-click menu of the header: 1. "Total Items": shows the sum of subfolders and files in total and recursively, 2. "Number of Subelements": shows the number of files and subfolders a folder contains directly. (Your request in feature voting)
Improvements:
TreeSize can now also use the user currently logged in to Windows to log in to SharePoint (integrated Windows authentication).
File search: The user interface for creating and editing search filters has been further improved. For combined filters, it is now even clearer which filters belong together and how they are linked. Individual filters can now also be adjusted or deleted directly via an overlay menu.
File search: The "Empty folders" filter template has been improved.
The TreeSize Duplicate Search is now available in the Windows File Explorer context menu. (Your request in feature voting)
Information required for an export is now increasingly determined asynchronously to speed up the export. (Your request in feature voting)
General memory usage reduced: TreeSize now discards unnecessary scan information early during automated exports, significantly lowering memory consumption for exports. Using /PrefetchFiles False, asynchronous preloading can be disabled, further reducing memory requirements but increasing export duration.
TreeSize now also supports large folders in SharePoint libraries that contain more than 5,000 items.
Azure Blob Storages can now be accessed directly via the URL displayed in the web browser.
File search: The error messages for failed deduplications have been improved.
File search: Search paths that are not checked are now retained when switching between searches and are no longer removed for the current session.
File operations: When using the log or undo script function, the information is now automatically written to an alternative file if access to the specified file is not possible.

New in TreeSize Professional 9.0.3 Build 1852 (Aug 25, 2023)

New in TreeSize Professional 9.0.2 Build 1843 (Jul 27, 2023)

New in TreeSize Professional 9.0.1 Build 1830 (Jun 23, 2023)

New in TreeSize Professional 9.0.0 Build 1822 (May 30, 2023)

Main Module / General:
TreeSize now supports the scanning and searching of mailboxes that are included in a locally installed Outlook. This includes IMAP as well as Exchange and Exchange-Online mailboxes. (Your request in feature voting)
SQLite was added as a new export format for scans. As an alternative and successor of the XML export, this format offers the possibility to export, import and compare scans on a single file level. Thus, a comparison of different scans down to file level is now possible.
TreeSize supports Scanning and browsing of Azure Blob Storage. (Your request in feature voting)
The demo version of TreeSize can now be activated by entering a license key and then becomes a full version. This requires an internet connection. The version available in our customers area can still be installed without an internet connection.
The component for sending emails has been replaced. With the help of the new component, OAuth2.0 authentication is now supported.
The application mode (Simple, Normal, Expert) can now be configured via the administrative templates as well. That way large organizations can preconfigure a mode for the users when rolling out TreeSize.
In the directory tree the Enter key opens not only files but also folders in the configured file manager, usually in Windows Explorer.
The user interface is now also available in Turkish and Slovak.
Improvements:
By means of a new comparison method for the duplicate search, files with "similar names" or identical name stem can now also be found. This comparison method recognizes file names as similar whose naming indicates multiple versions, such as: "Presentation Department V1.ppt", "Presentation Department V2.ppt"
The context menu for copying to the clipboard has been extended by additional options: the containing folder path and the file name can now also be copied. (Your request in feature voting)
The search performance for certain search filter combinations has been significantly improved. For example, a search that uses a long list of "owners" as filter now takes only a fraction of the original time.
The "Permissions" filter now also supports searching for files without "effective access rights". This means that a user has no access permission for the specified operation. This can be the case either because there is an explicit entry "Deny access" or because there is no matching "Allow permission" entry.
The user interface has been revised. The navigation elements on the left side now make it even clearer which of the stored search definitions are currently active.
The TreeSize file search now stores the search paths per search instead of globally for all searches. This increases flexibility by allowing you to store different combinations of search parameters and search paths. Based on feedback from our users, we believe this change will be useful for most users. If this is not the case for you, we would be very happy to hear about your use case.
The dropdown for selecting search paths now allows you to pin individual paths explicitly. This way, frequently used paths will stay there, even if they are not selected as search paths.
Bugfixes:
An error when deleting files in the “Top Files” list during a running scan has been fixed.
When scanning user profiles in the file system, an infinite loop could occur under certain circumstances. This error has been fixed.
A bug that prevented renaming rules of the new case-sensitive type from being edited has been fixed.
A bug that could cause files, that were previously renamed, to be renamed again under certain conditions has been fixed.
An error when creating new folders with special characters on SharePoint has been fixed.
An error when uploading files with the special characters % or # in their names to SharePoint has been fixed.
A problem in the display of compared scans was fixed. Deleted folders are now displayed as such again.
An error in editing scheduled tasks configured for multiple scan paths has been fixed.
Multiple addresses separated by a semicolon can now be specified in the input field for e-mail recipients again.
The new function for adjusting the case in the mass renaming dialog is now correctly applied to the selected part of the file name.
An error when comparing two saved scans of all SharePoint SiteCollections has been fixed.
Several other minor fixes and improvements have been made.

New in TreeSize Professional 8.6.1 Build 1764 (Feb 9, 2023)

New in TreeSize Professional 8.6.0 Build 1757 (Jan 5, 2023)

Main Module / General:
You can now select scan targets other than the Windows file system (e.g. SharePoint, Amazon S3, SSH, etc.) for comparison under "Scan > Compare with Path". The (size) differences are then displayed. This can be handy, for example, after migrating a directory system to check it for changes.
When updating a folder or scan that has been compared with another folder or scan, the comparison folder is now also updated.
You can now find TreeSize on top level in the new context menu of Windows 11.
The log file that can be activated in the file operations dialog has been completely revised. If CSV is selected as logging format, the information is now logged in well-structured in separate columns.
The new command line parameter /ShowAuthGui can now be used to force login dialogs to be displayed, even if TreeSize itself was started without a user interface.
When exporting the pie chart of file types, an empty chart could be exported under certain circumstances. This error has been fixed.
Mass Renaming:
The mass renaming dialog has been extended by a function to convert file and directory names to upper and lower case.
An option has been added to the mass renaming dialog to evaluate position values from the right. For example, it is now possible to delete the last X characters from a file name.
The mass renaming dialog now supports regular expressions when deleting specific text from file names.
The file name preview window in the mass renaming dialog has been extended by several functions that can be used to export the current overview to the clipboard or to a file.
File Search:
The current sort order of a result list is now saved and restored when the application is restarted. Under "View" there are additional options to customize the sorting, including an option to remove the currently set sorting again.
The selection for usernames in the new "Permissions" filter now includes user groups.
Refreshing the user interface after deduplication could cause freezing. This problem has been fixed.

New in TreeSize Professional 8.5.2 Build 1715 (Nov 24, 2022)

New in TreeSize Professional 8.5.0 Build 1707 (Oct 25, 2022)

TreeSize Main Application / General:
The feature to change the file owner, which was already included in the File Search, is now also available in the Details list of the TreeSize main application.
Portable Installation: If you select a target via "Tools > Create Portable Installation" on which you have already installed TreeSize portable before, the user settings are no longer overwritten there. (Professional edition only)
In the columns showing permissions, the users and groups are now displayed in alphabetical order.
The scan overview directly below the ribbon bar is now also hidden in simple mode for a more focused display. This overview bar can still be shown and hidden via on the ribbon bar "View".
The Details list now indicates possible access errors when displaying folders, instead of simply showing such folders as empty.
When copying or moving files with the options "Preserve directory structure, starting at level X" and "Apply timestamps for each item" enabled, the timestamps (last modified date) of the source folders are now also applied to newly created folders.
By pressing the Shift-Tate during a delete operation, selected objects can be deleted permanently, just like in Windows Explorer.An error that occurred when scanning a disk mounted in a folder has been fixed.
The command line option “/ShowCheckForUpdate False” now hides the update check buttons again as expected.
File Search:
A new f filter is now available to search for permissions in file systems. For example, all files or folders to which a user or group has read or write access to, can be listed. Your wish in our feature voting platform!
Two new search templates have been added to illustrate the new search in permissions feature.
The performance of deduplication has been significantly improved.
A new feature has been added to lock specific paths and files. Locked files cannot be marked for a delete operation. This can be used to prevent certain files from being accidentally deleted. Your wish in our feature voting platform!
Similar to the main application of TreeSize, the File Search now also supports three different program modes: "Expert", "Normal" and "Simple".
The function for importing file paths has been improved and now works much faster if the checkbox to import only valid paths is checked.
The progress bar in the lower right corner of the application now shows the progress of the file search, allowing the user to estimate how long a search will take. Statistics from past searches are used for this purpose.
The component for creating search filters has been extended in the right-click menu by the possibility to invert / negate existing filters. This is a convenient way to change a filter for including certain elements into a filter for excluding them from the result set.
A new column "Average file size" can now be displayed in the duplicate search. Your wish in our feature voting platform!
The length of the file name can now be used for a search. It can be selected in the search filter selection under "More search filters". The filter only looks at the name and not the path of a file. Your wish in our feature voting platform!
When running a scheduled TreeSize task, exports or file operations were not executed in certain situations. This error has been fixed.
When searching for duplicate files or unique files, an unhandled error could occur under certain circumstances. This problem has been fixed.
An error that caused filters of the "Name of a parent folder" type not to return all the desired results has now been fixed.

New in TreeSize Professional 8.4.0 Build 1710 (Aug 10, 2022)

New features:
A wizard for new users has been added, which guides you step by step through TreeSize.
TreeSize now has 3 program modes: "Expert", "Normal" and "Simple". New is especially the “Simple Mode", which aims at casual users with basic knowledge. TreeSize hides functions and settings that are primarily intended for system administrators, in order to provide a cleaner user interface. The "Expert" mode, on the other hand, shows less frequently used settings for power users in the options dialog.
Copying and pasting folders via the clipboard is now also supported between local scans and remote storage locations such as SharePoint, Amazon S3 or SSH.
File Search:
Using a single search has been made easier. A search can now be started and stopped independently of the rest. When starting a search (for example "Duplicate Search"), the results of the other searches (for example "Simple Search") are no longer discarded, but only those of the started search.
In the file operations dialogue, the option 'Replace only older existing files' is now also available when moving files to Amazon S3, SharePoint or Linux/Unix servers.
The search syntax of the 'Simple Search' now offers the 'path:' property, which can be used to restrict the search to specific folder paths. More detailed information and examples can be found in the program help.
The "Highest search results only" function of the advanced search has been improved. Filtering the results now runs much faster and no longer leads to a short-term blocking of the user interface.
The function "Select > Duplicates if a copy exists in folder" has been extended so that any folder can now be selected.
For the duplicate search, a new option "Mark > All except selected" has been added. With this feature, numerous files can be marked for deletion in one step, while the selected file remains.
Search filters can now be imported or exported from a file using the right-click menu. In addition, a simple list of file names or paths can now be pasted from the clipboard.
The filter "file extension" has been added to the list of available search filters.
The search for file content can now also search for terms with special characters in UTF-8 encoded files *without* the so-called "Byte Order Mark".
When deduplicating, duplicate groups were only included in the operation if all included files were check-marked. This has been fixed so that individual duplicates can now be check-marked for deduplication again.
The command line option /READONLYMODE "True" is now also correctly evaluated in the file search.
The duplicate search can now also read and process all files correctly in combination with the option "Search within ZIP files".
Improvements:
The dropdown at the top left of the main window with the last examined paths now enlarges if it contains very long paths, e.g. URLs.
In the options, up to 64 threads can now be set for a scan in "Expert" mode. Please use this option with care, because many threads working in parallel only make a scan faster if not other factors represent a bottleneck for a scan, otherwise a scan with many threads may become even slower.
In the dialogue for automated tasks, the value for "Next execution" is now displayed.
The optional column "Status" now correctly displays the OneDrive file status as text representation. This column can be activated via the "More columns" dialog in the right-click menu of the column header and contains data only for OneDrive folders for which the option "Files on demand" is activated.
The free space of folders on which Folder Quotas are defined now takes them into account, as it was in V7. In V8, until now, the free space of the entire drive was displayed. You see this value in the status bar, in the optional column "Free space" of the details list, as well as in the tooltip of the directory tree.
When renaming files, only the file name is now selected by default, but no longer the file extension, similar to Windows Explorer.
If a non-initialized network drive is scanned (labeled by a red X), TreeSize now tries to initialize it.
The function to expand to a certain level now folds deeper levels correctly again.
A problem with the display of size changes for individual files has been fixed.
Numerous other minor corrections and improvements have been made.

New in TreeSize Professional 8.3.2 Build 1665 (Apr 13, 2022)

New in TreeSize Professional 8.3.1 Build 1661 (Mar 17, 2022)

New in TreeSize Professional 8.3.0 Build 1658 (Mar 4, 2022)

File Search:
The duplicate search now also supports a mode to find unique files, i.e. files that have exactly no duplicates. For example, for migrations or backups, you can ensure that two folders are exact copies of each other, even if they are on technically different systems. To do this, simply select "Unique files" as search mode instead of "Duplicate files" or "Duplicate folders".
The search for duplicate folders has been optimized. Results are now found and displayed even faster.
Special search filters, such as "Number of pages" for Office files or the width and height of images, can now perform numerical comparisons. Likewise, time intervals can be used to search for date-based filters, such as "Last saved". You can access these by clicking the "More" item at the end of the search criteria drop-down list.
It is now possible to create new search templates and save them permanently, or to customize existing search templates.
The language syntax of the "Simple Search" now offers the property "size:", which can be used to restrict the search to certain file sizes. More detailed information and examples can be found in the program help.
The "accessed:", "created:" and "modified:" properties can now be used in the "Simple Search" to restrict the search to specific time intervals using the language syntax. More detailed information and examples can be found in the program help.
Result lists can now also be sorted by their checked state, so that all checked files are arranged together at the top of the list.
When exporting duplicate search result lists to a CSV file, an additional column is now added to make the group membership of the files clear.
Search filters can now be easily reordered using drag and drop.
The area for creating and editing search filters can now be expanded and collapsed.
Main module:
The icons in the user interface have been redesigned for a more modern Windows 11 style look.
The ability to add scan filters in the options has been renewed. The new dialog is more user-friendly and offers additional functions for combining filters. More metadata is now available for filtering.
A scan in progress can now also be paused and resumed. This was the feature request with the most votes on our feature voting platform.
The scan speed has been increased, especially when many threads are used for scanning.
SharePoint scans now supports multi-factor authentication using a certificate file.
The TreeSize bulk renamer can now be started directly from a shortcut in the Windows Start menu.
Bulk Rename of files and folders now also supports exporting and importing rules to a file.
Using the new command line parameter "/CSV" you can now explicitly distinguish between text and CSV format, regardless of the selected file extension. (Professional edition only)
The costs incurred for the used disk space can now also be displayed in a separate column in the statistics for file types, users and file age, as well as for the top files.
Archive files in ZIP, VHD, VHDX or ISO format can now be dragged into the background of the directory tree just like folders in order to analyze them with TreeSize.
TreeSize is now also available in Norwegian and Polish.
The "Top 100 Files" have been renamed to "Top Files" and can now be found under the new name in the user interface and help.
When starting the file search from the main module for a group of scans, all scan targets of the group are now correctly created in the TreeSize file search again.
The FTP protocol is no longer supported, as already announced in the V8.2 release. Please use the SSH protocol.
When applying NTFS compression to a folder, not all subfolders and files were compressed. This problem has been fixed.
Virtual disks can now be accessed by multiple TreeSize instances in parallel.
File operations dialog: Fixed an error when creating the undo script, previously created symlinks/hardlinks were not properly deleted.
When sending reports via email, a possible error in communication with MS Outlook was fixed.

File Search: The duplicate search now additionally allows finding duplicate directories. This is a Community Feature - learn more.
File Search: A new option "Search ZIP files" allows searching for files that are part of a ZIP archive. This is a Community Feature - learn more.
TreeSize now supports scanning drive images in VHDX, VHD and ISO format. To enter the path, you can use the corresponding image file just like a folder. This is a Community Feature - learn more.
A new column "Cost" hast been introduced for the "Details" list and all available export types. It can be used to easily calculate costs for occupied server space and e.g. break them down to department level. You can configure the used value and unit to calculate the cost in the TreeSize options.
Moving or copying files to a ZIP archive is now also supported for remote locations such as SharePoint, Amazon S3 or SSH as destination.
Intermediate results of subfolders are now immediately included in the displayed results. Previously they were added after the complete subtree has been scanned.
The Top-100 list now shows intermediate results while the scan is running. The final results are of course available at the end of a scan, when TreeSize has seen all files.
The scan history is no longer stored in an XML file, but in a SQLite database file. This reduced both the loading time of the history in the user interface and its size on disk.
The drive overview now optionally displays a column for the occupied disk space. Furthermore, the drive name can optionally be displayed in addition to the drive letter.
Automated tasks can now also be created with the option "Start with highest privileges" to start them "As administrator".
When navigating to the parent folder, the previously active folder is now selected in the Details list, as known from the Windows File Explorer.
Searching for files of a file age has been simplified and can now be started directly from the file age statistics.
File Search: Result lists sent by email are now sent by default as attachments and not as content of the mail. This means that even large result lists can be sent by email without any problems. This setting can be adjusted in the options dialog.
File search: The context and ribbon menu for selecting specific files has been revised. The clarity of the menu has been improved and new options provide additional functions for marking specific results in the list.
File search: The menu bar has been restructured. The clarity of the various functions and options has been significantly improved.
File search: A new function "Mark duplicates of files in folder" has been added. With this function, it is possible to mark only those duplicates that also exist in a certain directory.
File search: The user interface for editing search filters has been further improved. When creating and editing search filters, the size of the input fields can now be adjusted with the mouse.
File search: A new option has been added that allows folding out directories in the search results.
File search: Performance improvement: Exclusion filters for a specific "Absolute path" now prevent these directories from being searched. Previously, they were still searched and merely excluded from the search results.
The "Pass items to executable as parameters" function in the file operations dialog no longer passes the items sequentially but in parallel to the executable program to improve the processing speed.
Destination paths specified in the file operations dialog are now converted to UNC notation if they refer to a mapped network drive. This affects all actions performed using the file operations dialog.
When copying or moving files with the "Preserve directory structure, starting at level X" and "Apply timestamps for each item" options enabled, the timestamps (last modification date) of the source folders are now also applied to newly created folders.
When copying or moving files with the options "Preserve directory structure, from level X" and "Apply permissions for each item" enabled, the access permissions of the source folders are now also applied to newly created folders.
TreeSize now supports paths to SharePoint pages as they can be copied directly from the browser URL.
For certain files on SharePoint Online, TreeSize previously displayed the date they were saved on the SharePoint. TreeSize now uses the same values here as can be viewed online in the "Modified" column.
The function "Print right pane" now also includes a visible diagram, if one is enabled. The list alone can still be printed via the context menu of the list.
For the function to change the owner of multiple files, there is now a button in the ribbon bar in addition to the context menu entry.
File search: When executing the /DEDUPLICATE command line parameter, the full list of duplicates is now deduplicated again as expected.
SSH scans now support the EdDSA host key algorithm Ed25519.
Bugfix: A bug with calculating MD5 and SHA256 values via SSH was fixed.
Bugfix: A problem with displaying Chinese characters in exported PDF files was fixed.
Bugfix: When copying or moving multiple files within an SSH (Linux/Unix) scan, not all files could be copied/moved under certain circumstances. This problem has been fixed.
Changed compatibilities:
TreeSize now requires .NET Framework 4.8, which should already be installed on most systems via Windows Update.
Windows 7 and Windows Server 2008R2 are no longer supported, so at least Windows 8.1 or Windows Server 2012 is now required. Older versions of TreeSize that support older operating systems can be downloaded from our customer area.
We plan to end support for the FTP protocol with V8.3, because we believe that wherever FTP is possible, the more modern and secure SSH protocol is also usable. If we are wrong with this assumption, we would be happy to hear from you. On our feature voting platform there is also an entry for the support of the modern SFTP / SCP protocol.

TreeSize now has a dark mode, i.e. a dark theme for the user interface. Its activation can either be linked to the Windows setting for the dark theme, or it can be switched on and off specifically.
TreeSize now supports the enumeration of ZIP files. To use a ZIP-file, you can use the path to the ZIP file just like a folder.
The option to copy the file list of a file type is now also available for file groups.
The option to generate an expandable Excel report ("File > Options > Export > Excel") now also affects the export of the list of file types, whose file groups are also fold-out. Analogously, such an option can be activated in the TreeSize File Search options for the Duplicate search.
Date values can now also be displayed in the internationally standardized ISO date format.
The File Operations dialog now has an option to preserve the timestamps (creation date, modification date, last access) of files when performing a copy or move operation on the file system.
File search: The new "Templates" function replaces predefined searches like "Oldest files", or "Largest files". A new drop-down list contains a variety of predefined templates that serve as a starting point for a new, fully customizable user-defined search.

Benefit from the fast TreeSize search engine, the many supported search targets including the cloud, the numerous export formats for the results and the powerful file operations that can be applied to them.
File search: The user interface for search filters has been completely redesigned to improve appearance and usability. Search criteria such as file name, size, or age can now be freely defined in a central location and even combined as desired.
File search: A new option that allows to display the highest search hit per directory branch in the directory hierarchy has been added. Subfolders or files of a folder are no longer displayed as search results if the entire folder meets the search conditions.
Administrators can now define default settings for various options via the Windows Registry. These will then be used instead of the factory settings when TreeSize is started for the first time or when resetting the options. For easier configuration of these options, administrative templates are available for the Windows Group Policy Editor. More information and downloads can be found in the online help.
Inaccessible paths in the drive list are now shown disabled.
The suggested file name for the export file is now derived from the path to be exported.
TreeSize now displays a warning when moving files or folders from a system directory, as it does when deleting. This also applies to the File Operations dialog.

File Search: The columns "Number of versions" and "Volume name" are now also available in the dialog for additional search filters.
File Search: A potential error when deleting or moving files in the demo version was fixed.
Sorting by the number of versions now works as expected.
In some cases, the row height of the last row of an Excel export was too small. This problem has been fixed.

Main module:
TreeSize now supports the dedicated REST-interface for analyzing Sharepoint sites. By this, TreeSize can provide advanced functionalities, such as considering previous versions of files when calculating the „Allocated Space”, or allowing easier access to Sharepoint Online.
The Details list can now show and export all columns that are available in Windows Explorer as well, including image dimensions, “Number of Pages“ of Word documents, or tags inside JPG and Office files.
The scalability of the user interface in environments with multiple monitors and high DPI settings has been further improved. In addition to that, multiple adjustments and usability improvements have been included.
The column „Free Space“ is now available in the Details list and for exports.
It is now possible to create new empty folders and to rename existing files inside of Amazon S3 scans.
SSH scans now support more file operations, such as renaming folders from within TreeSize directly.
The dialog for creating scheduled TreeSize tasks now allows to add additional, arbitrary command line parameters.
Existing TreeSize tasks can now be duplicated. They can also be exported to and imported from a file.
Export settings for the size unit are now considered for single list exports, such as the “Extensions”, or the “Users” statistic as well.
Bugfix: A possible issue during the deletion of files on a mobile device has been corrected.
Bugfix: Renaming a file or folder on SharePoint Online will no longer trigger an error message.
Bugfix: In certain cases, the content of OneDrive folders was not shown correctly. This problem has been fixed.
A new column "Volume" that supplies the name of the volume a file or folder resides on is now available in the "More Columns" dialog, that can be accessed through the right click menu of column headers of the Details list and the result lists of the TreeSize FileSearch.
Bugfix: A possible application freeze when showing tooltips for network shares has been resolved.
XML reports containing paths that are located on high latency network drives are now loaded into TreeSize much faster.
Bugfix: TreeSize will now scan S3 buckets correctly that contain a “dot” in their name.
Bugfix: “Compare with snapshot” will now longer fail, if the name of a share contains whitespaces, or certain other special characters, such as the percent, or the equal sign.
The layout of exported HTML reports has been improved. This includes exports to HTML files as well as Email exports.
Several minor improvements and fixes have been included.
File Search:
A new dialog has been added, which allows to bulk rename multiple files at the same time. (Available in the Details list of the main module as well)
The Custom Search now supports searching for any file information that can be shown in the columns of the result list. This, for instance, allows to search for MP3 files of a certain artist, or for images that have specific dimensions.
The “Duplicate Files” search now provides three additional comparison methods: “Name and Size” (compares files by using only their name and their file size), “Size only” (Compares files by their size), and “Name without Extension” (Identifies files with equal filenames, ignoring the file extension).
You can now search for file content using multiple search terms. The syntax for such a combined pattern is {pattern1;pattern2;pattern3}. TreeSize will find files that contain all of these search terms.
The ”Duplicates Files” search now supports an additional filter, which allows to exclude newer files from the search.
Search results can now be filtered more easily. A new option allows to remove search results without excluding them from the search permanently.
The new option “Skip offline files in searches that access file content” can be activated in order to prevent TreeSize from triggering the download of offline files. Otherwise, TreeSize would need to download the file in order to access its content when running a search for file content or a search for duplicates.
Bugfix: An occasional memory problem during the search for file content has been resolved.
The usability of several components, such as the dialog for selecting date intervals, or the configuration dialog of file operations, has been improved.
Bugfix: Using the option “Delete empty directories after the operation” could lead to an application freeze. This issue has been fixed.
Compatibility changes:
.Net Framework: 4.5 or higher is mandatory. Please note: In rare cases, when the framework is not installed yet, our installer will automatically download and install it.

It is now possible to scan your Amazon S3 Storage using TreeSize.
It is now possible to scan Linux/Unix-servers via SSH-protocol using TreeSize.
It is now possible to add single file types or users as columns to the “Details” view using their context menu. That way they can be easily monitored across the entire folder hierarchy and can also be included in the reports.
Intervals of the Age of Files statistics can now be added as columns to the “Details” view using their context menu.
The number of files in the Top 100 list can now be configured in the Options dialog. Additionally you can choose here whether they will be chosen based on their plain file size or the space they actually occupy on the disk.
A new checkbox on the ribbon bar “View” allows to hide empty folders. This is particularly useful if there a lot of such folders because a filter has been applied.
Beneath the user and the file extension statistics we show a treemap chart now, because it is able to transport more information on the same area as the old bar chart.
We added two additional formats for displaying usernames: Full Name, and Username (Full Name)
A new tooltip option allows you to peek into a folder without actually expanding the folder in the directory tree.
TreeSize may now optionally show a message in the Windows system tray, once a longer running scan or file search is finished.
The treemap chart has been extended with many new display options:
oSingle files can be displayed now.
oBesides the file types now the file type groups like „Office files“ or “Video files” can be optionally shown as intermediate level. If shown, they will be colored by type, not by their level like the folders.
oThe free space can optionally be shown as separate tile.
oOptionally the labels can be hidden so that no space needs to be reserved for them.
At „Options > Scan > Filter“ you can now choose entire file type groups like „Office files“ or „Video files“ as filter, just like this is now possible in the Custom Search (see below).
When scheduling a scan you may now choose a monthly interval. (Professional edition only)
The user interface is no longer blocked when loading or comparing with a formerly saved XML file.
The column width of PDF exports can now be configured in the Options dialog.

Multiple custom searches can now be defined and used concurrently.
The minimal and maximal directory depth can now be used as search criteria in the custom search.
The predefined searches like “Biggest Files” now have their own ribbon bar, in which the configuration for this search is done now.
It is now more comfortable to choose date values in the Custom Search.
The feature “Checkmark if…” now offers more possibilities and regular expressions.
The TreeSize File Search now supports PDF export too.
The number of errors (like “Access denied”), which occurred during the search, is now displayed in the status bar. Clicking it brings up a dialog with further details.
Duplicate Search: The duplicates can be exported optionally with groups now. Such a text file can now be properly imported to the duplicate search.
Duplicate Search: In the dropdown menu of the button “Check all but newest” we now offer more functions to modify the check-state of the results. Here, an option can be activated that ensures that at least one duplicate remains after deleting duplicates.
The export of the Duplicate Search has been accelerated by factor 10.
A new option for scheduled searches will send an email only if results have actually been found for this search. (Professional edition only)
The command line option /SORTBY has been introduced, which is now also supported in the TreeSize File Search. (Professional edition only).

Please note: Files that are compressed using these new algorithms are not flagged as compressed by Windows in the file attributes.
A new option to deactivate the drag and drop features of TreeSize has been added to "Tools > Options > View > General" (requires activating the "expert mode" checkbox). Turning off drag and drop should prevent unwanted changes on critical systems.
The TreeSize task scheduler now supports specifying a text file containing the scan paths using the command line parameter /SCAN.
Bugfix: On some systems the folder dropdown box on the top left of the main window behaved strangely when typing a path or selecting a path. These issues have been corrected.
Bugfix: When using scheduled scans to export multiple reports to a PDF file, all reports (not only the latest) will be exported.

New in TreeSize Professional 6.0.0.907 (Sep 30, 2013)

CHANGES:
Faster scans:
The well-proven and extremely fast search technology of UltraSearch working directly on the NTFS file system structures has been incorporated to increase the performance of TreeSize Professional scans and searches on local drives.
64 Bit:
TreeSize is now available as native 64 bit application (Professional Edition only). When scanning very large file servers memory will no longer pose a restriction.
A new option allows making folders and [Files] items expandable and show single files in the directory tree.
New license keys will be issued for V6:
Please note: The old license keys for V5 provided on the license documents will not be valid for V6. The new license keys can be obtained in the customer area.
COMPARING / TREND ANALYSIS:
Compare using historic snapshots:
TreeSize Professional now facilitates comparing the current state of your local disk space with previous points in time using snapshots. No files need to be exported, even pre-existing snapshots that have been created by the system before TreeSize Professional was installed can be used for comparison. Additionally, TreeSize Professional offers an option to create a snapshot ("Tools > Create Snapshot").
Toggle between size growth and current size:
After performing a compare using an exported XML file or a snapshot you can now toggle between a comparison mode showing the size changes in all controls, and the mode showing the current values. In addition you can enable new columns ("Growth" and "% Growth") presenting the size increases and decreases in any of these modes on the "Details" tab. Those columns are not activated by default, but can be enabled using the context menu of the "Details" list header.
USER INTERFACE:
On Windows Vista / Server 2008 and higher, a ribbon-style user interface is now used. We decided to use the Windows Ribbon Framework to create the new user interface for TreeSize Professional. The Windows Ribbon Framework is part of the operating system in Windows Vista and later and so ensures optimal support and integration also in future Windows versions. It is also used by MS Paint, MS WordPad, MS Movie Maker and the Windows 8 Explorer. On Windows XP/2003 you will still see the classic user interface with a main menu bar.
The "Options" dialog has been redesigned. Several new options especially for exporting have been added (see next section). A new checkbox "Expert mode" allows activating a mode that shows additional options that can be useful for experienced users.
The include/exclude filter in the "Options" dialog has been revised. It offers matching by regular expression, exact match, filtering by owner and offers a preview of the impact of a filter in an Explorer-like view.
Support for Windows Vista/7 style drag icons and drag hints has been added.
You can now search the directory tree for a specific file or folder ("Scan > Directory Tree > Find" / Shift+Ctrl+F).
The number of errors that occurred during a scan (e.g. access denied errors) is now shown in the status bar. Clicking it opens a dialog with detailed information regarding the errors.
EXPORT FEATURES:
The HTML export has been revised: When JavaScript is enabled, you will now see a dynamic view which allows expanding and collapsing each level of the folder structure. Subfolders are now properly indented. Folders are formatted as hyperlinks; clicking on them will open the folder
Email: Besides sending emails using your MAPI client it is now possible to send them through STMP as well. This is useful when sending emails from within scheduled tasks. The STMP setting can be configured at: "Tools > Options > Export > Email > Transport"
You can now choose whether file information for single files should be included in Excel, HTML, Text and Printed export ("Tools > Options > Export > Exported elements")
You can now choose whether an Excel export of the directory tree should support expandable / collapsible levels ("Tools > Options > Export > Excel > Expert Mode > Formatting")
The type of information exported to an XML file can now be configured
The Personal Edition now supports the same export features (Excel, HTML, and Text files) as the Professional Edition
FILE SEARCH:
Custom Search: The pattern editor of the custom file search has been revised. It now supports regular expressions and also allows users to search in the file content.
Custom Search: You can now search for both files and folders at the same time (tab "Size / Attributes").
Custom Search: You can now decide whether your search filters shall filter by the number of NTFS hardlinks of a file. The new options "Ignore NTFS Hardlinks" and "Minimum Number of Hardlinks" are located on the "Other filters" tab.
Duplicate Files: You can now define filters for the duplicate file search to include/exclude files whose file name, path or owner match certain patterns ("File Search > Duplicate Files > Filters"). Please note: Using a highly selective filter for the duplicate search will remarkably increase the performance of the search, since fewer files have to be compared.
Temporary Files: If all files contained in a directory are matching the temporary file search criteria, the result list will show only this directory on the first level. The directories identified as temporary can be expanded to show subfolders and files.
Move Checked Files: Added new option to create an undo-script for move and copy operations (section "Logging").
Move Checked Files: There is now an option to replace existing files instead of resolving the name conflict using an automatic renaming.
Move Checked Files: For move and copy operations you can now define the directory level that should be preserved from the source directory structure.
With the new function "Change File Owner" included in the right click menu of the search result list you can now easily set a new file owner for all selected files. This is very useful e.g. if you found a group of files with an invalid file owner.
You can now use wildcards when scanning servers using server names (e.g. \\serverA*\) or for scanning IPv4 class C nets (e.g. \\192.168.123.*).
The new columns "Allocated Space" and "Dir level" have been added to all search result lists. The new columns are deactivated by default but can be activated via the context menu of the result list header or through "View > Visible columns".
A new "master" checkbox for (un-)checking all objects in a result list has been added to the top left of the header line.
Internet Files: Added support for Google Chrome and enhanced support for latest versions of other browsers (IE, Firefox and Opera).
DRIVE LIST:
The Drive List now shows the S.M.A.R.T. status of the listed drives (if accessible). Drives at risk can be identified quickly this way.
The Drive List can now also be exported to an Excel file, either using the right click menu or the command line option /EXPORTDRIVELIST.
The Drive List now has its own menu bar which contains commonly used actions such as mapping a network drive. The menu is shown as a Ribbon context tab, as soon as the Drive List has been clicked. (Windows Vista and higher only)
The Drive List now supports importing a list of paths from the clipboard using the right click menu. The menu item will only be shown if the clipboard contains a valid path.
SCHEDULED SCANS / COMMAND LINE OPTIONS:
The dialog to create and edit scheduled TreeSize tasks has been revised and new options have been added. For example, scans can now be scheduled not only daily and weekly but also monthly and you can force not to show the user interface. In addition you can now choose if exports should be appended to existing files, choose a column by which the exports should be sorted, and supply an XML file including the configuration for the scan. Find a detailed description of the new "Schedule Tasks" dialog, including all options here.
The new command line option /USERFILTER has been added: It allows predefining the user by which the directory tree is filtered.
The command line parameter /NOUNITS now also prevents thousands separators in exported values.
With the new command line switch /AGEOFFILES you can export a textual representation of the "Age of Files" statistics.
Added command line parameters /SHORTDATEFORMAT, /HIDESMALLFOLDERS and /SORTTYPE.
MINOR CHANGES AND IMPROVEMENTS:
The path in which the history information is stored can now be adjusted. This allows sharing this file among several users / administrators.
The information on the history tab can now be exported or imported.
The new column "Link Target" has been added to the "Details" tab and all export options. Columns "User Comment" and "Title of Scan" have been removed. New columns are not activated by default, but can be enabled using the context menu of the list header or at "Tools > Options > Export".
The column "Permissions" now shows "full" instead of "+w+r+x" if a use has full access rights on a file or folder. This allows distinguishing if a user has just read/write privileges or full access to a folder (which includes changing security attributes and taking ownership).
After copying a file system object to the clipboard in the Windows Explorer using Ctrl+C, its full path will be pasted to the Folder dropdown box of TreeSize when pressing Ctrl+V.
When scanning an entire server using \\ServerName you no longer need to enable the virtual root folder to group the shares under a common folder.
Numerous further improvements have been incorporated.
BUG FIXES:
Bug fix: "File > Export > Send by Email" now works under Windows Vista/7 even if TreeSize was started as administrator and MS Outlook is the default email client.
Bug fix: On some Windows Vista based systems TreeSize got into a not responding state when getting back from screensaver.
Bug fix: An occasional problem with corrupt Excel exports in XLSX-format has been solved.
Several minor bug fixes have been incorporated.

The new columns "Inherited Permissions" and "Own Permissions" have been added to the "Details" tab and all export options. The column "Own permissions" simplifies finding folders that do not inherit all their permissions from their parent folder. Both columns are not activated by default, but can be enabled using the context menu of the list header or at "Tools > Options > Columns/Export"
The new column "Alternate Data Streams" in the Details list shows the size of NTFS alternate data streams in a file
The columns "Quota Limit" and "Quota Usage" have been added to the "Users" list. This allows a quick overview about the usage and limit of the Windows built-in quota features from within TreeSize Professional
The "File" menu now includes a list of recently scanned paths and recently saved XML reports
You can now scan paths like "S:\Users\R*" or "R:\*\MyVideos". Only one root folder will be created in this case

You may specify a log file that logs all performed operations in detail. Furthermore you may configure in detail how to handle duplicates that are not located on the same volume
File Search - Duplicates Files: When deduplicating files using hardlinks now a union set of the original access privileges is applied to the remaining file, so that all users can still access the resulting file
File Search - Oldest Search: You may now alternatively specify the minimum age of a file in number of days instead of a certain date
The saved XML reports now include the owner of each folder in case the file owner statistics was turned on in the Options of TreeSize Professional

Bug fix: The command line option /SCAN did not work in combination with /EXCEL and /SAVE
Bug fix: The command line option /TREEMAP did not work in combination with /NOGUI
Bug fix: Right clicking on a very large file could cause the application to freeze for several seconds as this triggered calculation of checksums shown in the "TreeSize" submenu of the right click menu
Numerous further improvements and a few minor bug fixes have been incorporated

TreeSize Professional has passed the "Compatible with Windows 7" logo test.
Introduced new toolbar buttons "Back" and "Forward". You can use these buttons to navigate like in the Windows Explorer.
In the directory edit field in the upper left corner of TreeSize Professional it is now possible to enter multiple paths at the same time by separating them using semicolons. Each of these paths may contain wildcards. Example: d:data;e:logfiles;h:user*
Top 100 List: Added columns Creation Date (by default visible), Attributes, Version, Permissions (by default not visible)
Added column "Full User Name" (by default visible) and "User Comment" (by default not visible) on the "Users" page. Use the column header context menu to adjust columns.
The "Printed Report" and the lists printed using the "Print" button above the "Details" list now also contain the icons.
Added possibility to export a subbranch of the scanned file system to the right click menu of every folder.
Under "Tools > Options > Columns / Export" there is a new export type for CSV files now. This way CSV files can now be configured independently from the text export.
You can now export the user settings to a file ("Tools > Options > Miscellaneous > Settings") and import them later, or provide them to another instance or user of TreeSize Professional. You can also reset the user settings to the factory settings here.
The drives panel is no longer blocking TreeSize Professional on startup for a while if an unreachable network path is included in the list.
Introduced new menu "Edit" to the main menu. It provides similar features like the Windows Explorer "Edit" menu and includes: "Cut", "Copy", "Paste", "Select All" and "Invert Selection".
F5 now only updates the "Details" list if the Details list is focused. Otherwise it will, like before, perform a rescan of the currently selected directory branch.
Improved progress dialogs when printing or exporting. They showed a wrong progress sometimes.
Added new command line option /OPTIONS to pass formerly exported user settings to the application. (Professional edition only)
The new command line switch /APPENDTOFILES will make TreeSize Professional to always append its output to existing files when exporting a list in text format. (Professional edition only)
In file names passed on the command line, e.g. for the Excel or XML export, now environment variables can be used. (Professional edition only)
Charts: The colors assigned to the chart are now memorized for the next start. The context menu of the chart has an option to reset the colors to their default values.
Charts: The bar and pie charts now also display Unicode characters.
Charts: All charts can now be copied, saved or printed through their right click menu.
Charts: Introduced new buttons in the toolbar of the "History" and "Age of Files" tab to (de)activate the gradient, patterns and hint marks.
Charts: In the right click menu of the pie chart you can now define the threshold for items to be merged in the "Others" slice.
Charts: You can now zoom the active chart by using the mouse wheel while the "Ctrl" key is pressed.
Charts: Saving to a PNG file is now supported.
Charts: You can now scroll the treemap by keeping the space bar pressed while dragging the treemap using the left mouse button, similar to imaging software (e.g. Photoshop).
A new feature "Manage Scheduled Tasks" has been added to the "Tools" menu of the main application and the File Search. It allows to edit or manage previously created TreeSize tasks. (Professional edition only)
Schedule TreeSize Tasks: Added "Execute this Task" to the right click menu of the "All Tasks" list and the box showing the current command line. (Professional edition only)
Schedule TreeSize Tasks: Added the new functions "Activate Task" and "Deactivate Task" to the context menu of the "All Tasks" page. This state is now also shown by the icon of each task in the list. (Professional edition only)
File Search: Use the new option "Tools > Schedule Current Search Options" to open the TreeSize Schedule Task dialog with the currently configured search settings. (Professional edition only)
File Search - Duplicate Files Search: Introduced new "Deduplicate Checked" button on the right side of the file search window. This button replaces all checked duplicates with links to the same file. If the files are on the same partition, then all files will be hardlinks to the same content. If creation of a hardlink is not possible, a symbolic link is used under Windows Vista and later. If this is not possible too, a Windows shortcut will be created instead as fallback.
File Search: Added column "Author" to the result lists which shows the author included in most MS Office files.
File Search - Move Checked Files: We enhanced the option "Leave shortcut at original location", so that you can now decide to leave a (hard) link instead of a Windows shortcut.
File Search - Move Checked Files: Introduced new option "Automatically rename existing files". If this option is activated, files will be automatically renamed if a file with the same name already exists in the destination.
File Search - Move Checked Files: We introduced a new option "Preserve directory structure". This option is activated by default, because the directory structure was preserved in former versions of TreeSize Professional. You can now deactivate this option to move files directly to the chosen destination. Existing files located in the destination will be renamed (e.g.: "..file.name" -> "..file.bak0.name") if the option "Automatically rename existing files" is activated.
File Search - Move Checked Files: When moving files from one drive to another, the creation date is now preserved.
File Search - Custom Search: You can now search for folders by checking the "Directory" attribute on the "Size/Attributes" tab.
File Search - Custom Search: You can now search for files and folders having the attribute for Reparse Points / Mountpoints set.
File Search: The command line options /SIZEUNIT and /NOUNITS are now also supported in the File Search. (Professional edition only)
File Search: The /FILTER command line option no longer sets the patterns for the temporary file search, it now sets the patterns of the custom file search and allows an easy file search for certain file types or patterns. (Professional edition only)
Bugfix: In the right click menu the "Open" command for folders ("Open containing folder" for files) did not work on 64Bit Windows systems.
Bugfix: File Search: When using the "Move Checked Files" function in combination with the "Preserve permissions of the original file" option, in rare cases an error could occur.
Bugfix: When editing the scheduled time or day or trigger type (once, daily, weekly) of an existing task in the "Schedule TreeSize Task" dialog ("Tools > Schedule TreeSize Task"), this change was not stored.
Bugfix: The command line option /TREEMAP was not working in combination with /NOGUI.
Bugfix: When terminating a duplicate file search with MD5 checksums before it was finished, the result list could incorrectly include some entries that were not checked for equal file content.
Many further enhancements and a few minor bug fixes have been incorporated.

New in TreeSize Professional 5.2.3.505 (Apr 3, 2009)

New in TreeSize Professional 5.2.2.493 (Feb 19, 2009)

New in TreeSize Professional 5.2.0.484 (Feb 6, 2009)

File Search: The "Move Checked Files" feature is now able to handle paths of more than 255 characters and optionally is able to preserve the permissions of the moved files.
File Search: The "Move Checked Files" feature as well as the /MOVETO command line option (Professional Edition only) now allow to pass the checked files to any executable file as parameter. This offers system administrators a lot of possibilities to manually and automatically process the search results of a TreeSize Professional File Search.
File Search: The search results can now be saved to a native Excel file. If multiple result lists are saved, each list will be placed on a separate sheet.
File Search: With a new option on the "Move Checked Files" dialog you can now automatically remove empty parent directories that are left over after moving / deleting the checked files.
File Search: In the list of search patterns of the "Custom Search" type it is now possible to use patterns that include fragments of a path, e.g.: "C:Windows**.exe" or "*Temp*.old"
File Search: The ZIP files created by the "Move Checked Files" feature are now able to store Unicode file and folder names in the ZIP file. ZIP files containing Unicode paths can only be unzipped properly by Unicode compatible ZIP tools like WinRar or WinZip.
File Search: It is now also possible to start the File Search with Full administrative privileges from the Windows "Start" menu and the "Tools" menu of TreeSize Professional.
File Search: In the "File" menu it is now possible to print a result list or to copy its contents to the clipboard. Use the right click menu of the lists to copy only the selected items.
File Search: It is now possible to copy the contents of the drive list to the clipboard using its right click menu.
File Search: The /DATE command line parameter is now also supported for the file search. This way you can automatically add the current date and time to file names specified for the /SAVE parameter or the /MOVETO parameter with a ZIP file. /DATE will change all file names that appear after its occurrence on the command line.
The new command line options /NOHEADERS and /NOUNITS allow to omit the headers and units from exported files, which simplifies getting plain data for later postprocessing.
A new option allows to exclude files that are marked as Offline. Offline files are often not physically present on the disk or are only cached temporarily on the local disk.
The new command line option /LISTSEPARATOR allows to define the separator that is used when exporting text files.
The new command line parameter /EXPORTDRIVELIST has been added, which saves the contents of the drives panel to a file.
Now the Excel 2007 format (file extension XLSX) is supported by TreeSize Professional. This enables you to export Excel files with more than 65,000 rows.
All Excel files saved by TreeSize Professional now have numbers and units separated, which simplifies performing calculations with size values. When saving the "Details" list to an Excel file now only the selected items will be saved if more than one item is selected.
All pattern editors (e.g. View > Options > Include/Exclude, the custom file search, etc.) now have checkboxes in front of their patterns. This allows to deactivate certain patterns temporarily without the need to delete them.
You can now choose to install the Professional Edition as portable version, e.g. on an USB stick. The settings are stored in the application path in this case.
TreeSize Professional now stores the user settings in an XML file in the user's profile.
Treemap: Added OLE drag support to the treemap chart. Drop support will follow in the next version. This allows dragging folders from the treemap to other locations.
Treemap: Ctrl + und Ctrl - can now be used to zoom the treemap. The cursor keys, Home, End, PgUp and PgDown can be used to scroll the zoomed chart.
Added a context menu item that allows to copy the underlying data from the "Age of Files" chart to the clipboard as text.
Ctrl+X now executes the Windows Explorer "Cut" operation in the directory tree and the "Details" list. The keyboard shortcut for "Automatic Units" has been reassigned to Ctrl+U.
When saving a scan to an XML file, the XML stylesheet is now copied next to the exported XML file and is referenced using a relative path. This simplifies using the XML files on systems not having TreeSize Professional installed.
Several minor improvements and bugfixes on the treemap, the bar and the pie charts.
The memory consumption for storing the file types and the user statistics has been reduced.
Bugfix: In the "Duplicate Files" search, when checking all selected items using the context menu (if file group items get selected as well) the check state of the group items was set too, which resulted in an error when using the "Move Checked Files" function.
Bugfix: Fixed a memory leak that occurred on Windows Vista when scanning with the option "Track NTFS Alternate Data Streams and Hardlinks" activated.
Bugfix: It is now also possible to pass domains and servers like \domain or \server at the command line. Previously this worked in the user interface but caused an error message at the command line.
Many further enhancements and a few minor bug fixes have been incorporated.

New in TreeSize Professional 5.1.2.433 (Jul 28, 2008)

New in TreeSize Professional 5.1.1.418 (Apr 19, 2008)

New in TreeSize Professional 5.0.0.380 (Nov 28, 2007)

It is now possible to group scans under a virtual root folder. This virtual root folder shows a summary of all scans that are part of this group. This way you can merge different scans together e.g. for printing or exporting. You can access this feature through the context menu of a root folder or through the "Tools" menu.
A new kind of chart called treemap has been added. It shows a hierarchical view of the file system. In this treemap chart each folder is shown as a rectangle with its subfolders inside, again as rectangles.
The list on the "Extensions" tab can now be grouped by file types like "Audio Files", "Video Files", "System Files", etc. This feature can be turned on or off by a new toolbar button.
The tabs "Extensions", "Users" and "File Ages" now have a feature "List Files" that generates a list of files of the selected item.
The selected items in the various file and directory lists of TreeSize now show the selection using a style similar to Windows Vista. This makes colored text and the small embedded charts easier to read.
The TreeSize column for the Windows Explorer is now also supported on 64Bit systems. The .NET Framework 2.0 is required on 64Bit systems for the column to work. Unfortunately a Microsoft employee confirmed that such an additional Explorer column won't be possible under Windows Vista.
The number of decimals can now be set in the View menu instead of the "Options" dialog.
The gradient colors of the optional indicator bars in the tree can now be chosen in the "Options" dialog.
In the Options dialog you can now change the maximum number of threads that TreeSize Professional 5 creates for each scan. Like before TreeSize Professional 5 will still adjust the number of threads to the current system load and so often create less threads than the maximum number.
In the Options it is now possible to customize the intervals that are used to generate the chart on the "File Ages" tab.
TreeSize Professional 5 has a new option that allows taking hard links and alternate data streams into account when calculating disk space, which produces more accurate results. However this makes it necessary to open the files and therefore slows down a scan.
The "View" menu now allows switching to plain Byte values.
The Excel, Text and HTML export options now allow to specify whether or not units like "KB", "MB" or "%" should be added to exported values. By omitting units the thousands separators will also be omitted, which simplifies further processing of exported values. This replaces the former option File / Export / Use plain numbers.
The command line options /FILEAGESCHART and /HISTORYCHART have been added. They allow to save the charts on the "History" and the "File Ages" chart.
The new command line option /TOPFILESLIST allows exporting the top 100 files list.
The columns of the "Copy list of files" feature are now determined by the settings for the "Text Export" in the "Options" dialog of TreeSize
The executable has been renamed to "TreeSize.exe".
The support for Windows 98 and ME has been dropped. Registered customers are still able to download the Windows 98/ME compatible TreeSize V4 from our customers area.
New application icon.
An additional search type "Custom Search" has been added. This search type allows you to freely define and combine search criteria like file name, date, size, attributes and owner. The results can be printed or exported like you are used from the other available search types.
Now entire servers, entire domains or even your entire network can be searched. TreeSize automatically browses for PCs and all shares on them (including hidden shares) and performs the search on all shares that it finds.
Improved multithreading support, especially for the MD5 checksum calculation, which should produce results faster on multi-core machines.
It is now possible to export and import the results as simple paths only (DIR /B /S format). This simplifies post-processing of TreeSize results and allows to import lists of paths in TreeSize.
It is now possible to pass an XML file to the TreeSize File Search on the command line, which contains previously saved search options. This simplifies scheduled scans with predefined search options.
The Move operation now optionally logs the performed operations to a log file.
The result lists do now work as a source for drag and drop operations.
A new feature "Check all but Newest" has been added to the context menu of the duplicate file search results.
A new feature in the context menu of the duplicate file search allows to replace duplicate files with hard links. This way all the duplicate files remain at their position, but only one file occupies disk space.

New in TreeSize Professional 4.3.2 (May 28, 2007)

In the Options dialog (Tools / Options / Scan) you may now choose the priority for the scan and search threads. You may reduce their priority up to idle (use only unused CPU time), which allows you to run a scan with TreeSize without any impact on your PC or server.
The toolbar of the Top 100 Files List now contains a Delete button.
It now works under Windows Vista with Internet Explorer 7.
Formatting and performance have been improved.
Errors that occurred during the scan are now indicated by a small exclamation mark in front of the folder name.
If the option "Follow mount points and symbolic links" is turned on, then TreeSize follows only links that point outside the scanned directory tree. This prevents circular references and folders from being counted twice. The link target is now also shown in the long tooltip of the directory tree.
In the background of the directory tree a gradient now is shown for each folder that indicates its size in relation to the entire scanned file system tree. We hope you will like this new visualization of the folder size. If not, you may switch it off in the Options dialog.
The context menu of the file extensions and user statistics now have a menu item that allows to copy a list of files of the selected file type / user to the clipboard.
The user statistics now use a caching mechanism which significantly increases the performance of a scan with the users statistics activated and also reduces the traffic to the Windows domain controllers.
The new command line option /UNITTYPE allows to set the unit (KB, MB, GB) that should be used for displaying size values. For detailed information please see the help file.
The small arrow indicating symbolic links and reparse points is now also shown in the Details list. System and hidden folders are now shown "ghosted" like in the Windows Explorer.
The TreeSize File Search can now be started from the context menu of any folder in the directory tree.
File Search: A new search type allows you to search for duplicate files. Currently files with the same name, size and change date will be listed. This feature will be further improved in the next release.
File Search: It is now possible to save and load the options of the File Search to/from an XML file.
File Search: The cache files of the Opera browser are now also found by the search type "Internet Files".
File Search: The temporary file search now has an option that lists all files in the "Recent" folder of the user profile. This option is turned on by default. Although Windows shows only the last 15 entries in the "Recent Documents" folder, it keeps shortcuts to all files ever opened in the "Recent" folder which are quite useless.
File Search: The size and the number of checked files is now displayed in the status bar.
File Search: The Save dialog now has an option to save all result lists (instead of the active one only), as well as an option to save the checked files only.
File Search: The new command line option /MOVETO replaces /MOVETOZIP and allows, in addition to a ZIP file, a folder path or the Recycle Bin as destination to which the files will be moved. For detailed information please see the help file.
File Search: If "Add To Exclude List" is selected from the context menu, all matching search results are now immediately removed from the result lists.
File Search: In the View Options a new setting allows to adjust, if the compressed size or the normal size should be displayed for compressed files.
The support for Windows NT4 has been dropped.

New in TreeSize Professional 4.1 (Nov 6, 2006)

New in TreeSize Professional 4.0.2 (Aug 10, 2006)

New in TreeSize Professional 4.0 (Jun 3, 2006)

TreeSize now scans a file system branch with multiple threads. The number threads that are used is adjusted automatically dependant on the system load. Because of the latency of hard disks and network drives, this new feature drastically reduces the time necessary for scanning a file system branch.
In the New Dialog "Schedule Tasks" (Tools / Schedule Tasks) you can now add customized TreeSize Tasks to the Windows Scheduled Tasks.
The XML import, export and compare have been improved. All XML operations are much faster now and use considerably less memory. The size of the XML-files has been reduced as well.
The tree control was replaced with a faster one, which increases the performance of a scan and expand operations in the file system tree.
The tree now shows large hint windows that include detailed information about each node. This feature can be turned in the Options.
Most parts of TreeSize are now Unicode enabled under Windows NT/2000/XP/2003. Windows 98/ME are still supported, but with limited Unicode capabilities.
The Options dialog now has a checkbox, that let's you decide, whether or not TreeSize should appear in the Explorer context menu of Folders for the current user.
A new drive list box in the bottom left corner provides a quick information about the size and the free space of the local drives. Additional remote drives can be added using the context menu.
The top 100 largest files of the scanned path are now shown on an additional tab on the right pane.
Added support for file system Drag&Drop operations in the main window of TreeSize.
The HTML export is now UTF8-encoded and exports Unicode folder names correctly.
The extensions statistics now shows the Windows description and the corresponding icon for each file type.
In the Options you can now define what TreeSize should do when it starts without a path to scan. It may scan a list of fix paths, it may scan the paths that were active the last time it was used, or it may simply do nothing, which is the default behaviour.
Two new columns have been added that show the MS Office author and the MS Office last change date. These values get extracted from all MS Office files.
The context menu of the tree now allows to create a new folder. The shortcut for this operation is Ctrl N.
All percent values do now have a bar chart beneath them that indicates the percent value.
It is now possible to compress and decompress files and entire folders with NTFS compression using the context menu of TreeSize. The values inside TreeSize will be updated on-the-fly.
A style sheet can now be used with exported HTML files. The style sheet file can be specified under View / Options / Export / HTML.
The width of the columns in the printed reports can now be adjusted under View / Options / Columns / Printed Report.
A scan that has been opened and compared through command line options, can now again be exported through a command line option like /XML or /EXCEL.
A new menu item in the Help menu allows to check, if a newer version of TreeSize is available.
Several minor improvements have been added as well.
File Search:
The TreeSize File Search now uses multiple threads per drive which reduces the time that is needed for scanning a drive.
The list controls have been replaced with faster ones, which reduces the time needed during the scan as well as the time needed for move operations especially for a large number of results.
The selected items in a list can now be copied to the clipboard using the context menu.
The TreeSize File search does now fully support Unicode file and folder names. The speed and reliability of the "Move To" feature has been significantly improved.
The Move-To-Zip feature and the "Save Results" button now have a progress indicator.
The querying of the file owners can now be turned off in the View Options if not needed. Querying the file owner is a slow operation under Windows.
