Bursts, RAW + JPEG, duplicate imports.
The same vacation photo, three times, across Pictures, Downloads, Desktop. Dupe groups them with previews so you keep the right one.
Dupe scans your Mac for byte-for-byte duplicate files — the second copy of every photo, every screen recording you exported twice, every installer you forgot to throw away — and walks you through removing them. Always safe. Always your call.
Or get Dupe and 7 other apps with UnlimitedByte-for-byte identical files, surfaced as groups so you can keep one and tidy the rest. Native previews for everything.
The same vacation photo, three times, across Pictures, Downloads, Desktop. Dupe groups them with previews so you keep the right one.
Big files, twice. A 312 MB screen recording dropped twice in the same folder costs the same as a thousand photos.
You downloaded the Chrome installer six times. Dupe knows. Trash all but the latest.
The contract you saved into Documents, Downloads, and your Desktop, identical bytes each time.
The same album in iTunes Media and on the Desktop. Voice memos backed up twice. Two copies of the keynote.
Twelve projects with the same React lock-file. Old dist/ folders. Identical Docker volumes. Often the biggest pile.
Or pick your whole home directory. Dupe handles any scope, any depth.
Dupe hashes every file's contents. Same hash, same bytes, same file — even if the names differ.
Walk the groups. Keep one. Trash the rest. Watch the free-space number climb.

No. Dupe only ever suggests duplicates — you decide which one to keep. Anything trashed goes to your Mac's Trash and stays recoverable until you empty it.
Dupe computes a cryptographic hash of every file's contents. Two files with the same hash are byte-for-byte identical — same content, same size, same everything. No filename guessing, no fuzzy similarity, no false positives.
Those aren't byte-identical (RAW and JPEG are different formats), so Dupe won't flag them as duplicates. It only finds true copies. If you've imported the same JPEG twice into different folders, though — that, it'll catch.
As big as you like — whole home directories on multi-terabyte drives. Dupe streams hashes so memory stays flat. A typical home folder scans in two minutes on Apple Silicon.
