New in One Commander 3.70.1.0 (Mar 4, 2024)

  • Machine-based licenses are being retired (160-characters long). The existing Machine-based licenses will continue working for the lifetime of the PC, and "can be moved once within 1 year of purchase", per the original purchasing terms, but no new Machine-based licenses will be sold. It is possible to upgrade to User-based license that will work on any future PCs (and multiple PCs you might have today). Upgrade by clicking "Upgrade to User-Based license" from About dialog of the licensed PC. The upgrade currently costs $10 (price difference between User-based and Machine-based licenses) so nobody will be at a loss
  • This doesn't affect licenses starting with "LIC-" or "U-" or "DOMAIN-"
  • Taskmaster - OCs new files Copy/Move system (experimental - for testing only)
  • Use Alt+Drag menu to access the option to use Taskmaster
  • Teracopy is also added in Alt+Drag menu if it is installed, even if not registered as default
  • Additional option to set a different text rendering - mostly useful for low-PPI displays (under 100PPI). Look for red "NEW" flag in Settings??Advanced
  • Different file-icons and button-icons scaling to make it look better for low-PPI displays and multi-monitor setups with inconsistent display scale. It shouldn't affect quality on high-PPI screens
  • Fixed browser tabbing order
  • OneCommander Dialog Connector improvements for getting path from OC and terminating on OC close (Scoop update fix)
  • Removed an obsolete library
  • Small bugfixes

New in One Commander 3.69.1.0 (Feb 18, 2024)

  • Turkish translation thanks to Orhan Yalçın

  • Fixed setting accent color from color grid
  • Fixed issue with downloading video/audio from sites by enclosing URL in quotes
  • Fixed issue which created an additional tab when switching layouts
  • Fixed issue where last closed window wouldn't be the one that opens after a shutdown
  • Small bugfixes and typos

New in One Commander 3.68.1.0 (Feb 5, 2024)

  • If you ever had instances of program freezing while renaming a file on your PC there are several experimental workarounds in Settings🡢Advanced🡢Experimental. Look for 'Rename freezing workaround' and provided options 0-2 (0 is default, 'Rename through Explorer' is off by default due to Explorer's limit of 240 characters and slow update)
  • Different way of ensuring that there is a single instance of program running.
  • NOTE that this system not compatible with previous versions so if you are running older versions from different folders it won't be able to switch to the correct instance of the program
  • Fixed regression bug dropping items into .bat file

New in One Commander 3.67.1.0 (Feb 5, 2024)

New in One Commander 3.67.0.0 (Feb 5, 2024)

  • Editable list of file types (PRO) Settings??Advanced. This affects components like preview, metadata, thumbnails
  • For example: if file extension is in Video files list will be delegated to MediaPlayer component, and if Windows has a codec to preview that file type (either built-in or provided through 3rd party system extension), the player will be able to play it. There is no way to auto-detect this so the list is user-editable. Same is for audio files, pictures (to get resolution, preview), photos (to try getting camera metadata in second column of Adaptive view), etc
  • Drop file onto .ps1 or .py to run it with that script. Mouse over shows blue 'Open with' cursor
  • Editable list of 'Executable' script file types (mentioned above) (PRO only)
  • Editable double-click threshold (Settings??Advanced) to fix accidental mouse doubleclick (debounce time / noisy mouse buttons)
  • Disable double-click to open during Ctrl selection

New in One Commander 3.66.0.0 (Jan 18, 2024)

This was done also to prevent splashscreen getting stuck but I am not able to reproduce the issue, so it is not certain if this fixes that issue.

  • Press F2 in rename popup to toggle between selecting name and extension

New in One Commander 2.1.2.2 (Sep 24, 2018)

  • Due to a bug with Store Apps and ActiveX components, this update doesn’t use ActiveX in File Preview (Space bar). If the Windows has appropriate Shell Extension for generating thumbnails for a certain file type, an image preview will be generated. For example, in case of PDF files, user will not be able to flip through pages within Preview, but will be presented with only the first page of the file (Acrobat Reader or other PDF reader needs to be installed and thumbnail option enabled in settings). The Portable and ClickOnce versions of One Commander from this page still support ActiveX. Once Microsoft resolves this issue, the ActiveX preview will be reenabled.
  • Program Messages are by default now shown in TitleBar instead of slide-down message. Due to unknown WPF rendering framework crashing while displaying information in this panel on some computers, messages have been moved to Title Bar, but these can be reenabled in program Settings.
