My verdict:

  • The best result is from Duplicate Cleaner Free, though if you want fast, I suggest DupeGuru
  • Best for music: Similarity (I think DupeGuru Music Edition is very good as well)
  • Best for image: Auslogic, Similarity. (I think DupeGuru Picture is very good as well)

I still like Duplicate File Finder more (think it’s more accurate. It catches 2 files in picture mode in different dimension, not caught by DupeGuru PE. Still Dupe Guru is crazy fast.

About Ky

Currently Indonesian university student trying to submit more useful contents to share one's limited knowledge. Rather has wide, shallow interests, the writings will be as sporadic as it can be. Should write more scientific and field related topics, but writing muse says otherwise. Expect more on technical related writings especially softwares and apps, cultures, music, and random things.
