Portable Funduc Software Hex Editor

This is the portable edition of Hex Editor. Developed by Funduc Software, this app enables advanced users to directly examine and edit files of any type via hexadecimal display, export hex dumps, and set bookmarks, among other features.

Since there isn't a setup pack involved, the app directory can be saved to any location on the HDD to directly run the executable file, as well as copied to a mass storage device to use it on any machine without third-party installers.

Moreover, the Windows registry settings remain unchanged, and no extra files are created on the disk without the user's consent, thus leaving no traces behind after Hex Editor's removal.

It can be easily noticed that the program does not put emphasis on the visual aspect, adopting a standard interface with a familiar structure. Files can be opened via the file browser only, since drag-and-drop is unsupported. More files can be opened in multiple windows to easily toggle them.

Users may select any hexadecimal value to find out its offset and bits in the status bar, modify bits, append bytes at the end of the file, get floating values and Unicode text and copy them to the Clipboard for further usage, translate strings from UTF-8 encoding format, as well as view file properties in regard to the full path, file size, and number of hexdump lines (this information may be copied to the Clipboard as well).

Blocks can be selected either traditionally by using the cursor, or by specifying the start and end offset. A search-and-replace function is available to simplify the editing process, while bookmarks can be established for offsets.

As far as viewing options are concerned, users may toggle hex and character editing along with keyword insert and overwrite mode, enable read-only to prevent editing, choose the number of bytes to show per line and total characters for displaying the offset length, switch from ANSI to OEM character set and from Little-endian to Big-endian binary mode, as well as customize colors for the text, background, separators, selections, selection background, and bookmarks.

Selected blocks or the entire file can be saved, while the hexdump may be exported to file or copied to the Clipboard after pointing out the start and end offset.

The tool does not put a strain on PC performance, using low CPU and RAM. However, it hang several times during our tests when we attempted to insert new files. Otherwise, it features handy options for viewing and editing the hexadecimal code of files.
