Bytessence DuplicateFinder Portable

This is the portable edition of Bytessence DuplicateFinder, a resourceful application with intuitive options designed to locate and eliminate duplicate files, in order to increase the disk space and declutter the HDD.

As there is no installation pack involved, you can save the program files in any part of the HDD and just click the executable to launch the app. Another possibility is to save Bytessence DuplicateFinder to a USB flash disk or similar storage unit, to be able to run it on any PC effortlessly and without previous installers.

Worth taking into account is that the Windows registry and Start menu do not get updated with new entries, and no extra files are created on the disk, leaving it clean after removal.

The interface is easy to work with, since all main options are split into different areas in a wizard-like structure. You can specify the areas you want to scan, include subfolders and process empty files as well. It is possible to scan either all files types except the ones user-defined, or only the files with given extensions.

Bytessence DuplicateFinder Portable can be asked to take into account the date of creation, last access and modification, file attributes (read-only, system, archive, hidden, compressed), along with the file size (by indicating a minimum and maximum dimension). It can match results by various criteria, such as exact file contents or file names. You can study the search results where duplicates are put together with their original item in separate groups, and select the exact group or files you want eliminated.

Scan jobs may take a while to finish, depending on the size of the target and applied settings. We have not come across any difficulties in our tests, though, as Bytessence DuplicateFinder Portable did not hang, crash or pop up error messages. It is filled with customization settings that should meet the requirements of most users. Plus, it is free of charge.
