Local file deduplication

Find the copies.
Keep one. Take your space back.

DuplicateDuster hashes every file and finds exact duplicates — even ones that were renamed or moved — across as many folders and drives as you point it at. Multi-threaded for speed, entirely on your own machine, with nothing sent anywhere.

Exact-match certainty
01How it matches

One method, and it's never wrong.

DuplicateDuster hashes the actual content of every file with SHA-256. Two files with the same hash are byte-for-byte identical — there's no approximation, no scoring, and no false match. The filename never matters: a copy renamed or moved to a different folder is still recognised the moment its content matches.

What it catches

  • Exact, byte-for-byte duplicates anywhere in the scanned folders or drives
  • Copies that were renamed — the match is on content, not the filename
  • Copies moved to a different folder or drive
  • Any file type — hashing doesn't care what the file is

What it doesn't

  • A file that was re-saved, re-encoded, or edited — even by one byte — won't match
  • There's no "similar image" or "near-duplicate" detection
  • It compares files, not folder structure or metadata alone

We'd rather tell you the boundary than oversell it.
