I am seeking recommendations for a duplicate file finder for Windows with the following features:

  1. Portable (no writing to registry or outside of its own folder)
  2. Easy to add/remove folders and subfolders that will be searched without having to manually type in every folder name
  3. Shows date/time and folder for each result
  4. Can delete specific duplicate files from the results within the application
  5. No false-positives
  6. Works well with an OS dark theme.
  7. Gratis

I tried AllDup, but it failed for requirement #6.

I also tried the duplicate file finder in FreeCommander, but it failed for requirements #2 and #6.

Open-source is preferred, but not required. A simple binary comparison is fine.

I use CloneSpy.

Besides lack of dark mode, it ticks the rest of your requirements so would be worth a look.

You can set it to prompt (like the pic below), or just delete all duplicate files without confirmation.

  • Thanks KERR. I think the lack of compatibility with dark theme may be a deal-breaker on that one. The various "Search for" options look appealing though. Apr 21, 2021 at 10:35
