Reading photos
How it works
- Exact duplicatesFiles with the same size are compared by a SHA-256 fingerprint of their contents. Matches are the same photo, byte for byte.
- Look-alikesEach photo is shrunk to a tiny greyscale picture and turned into a 64-bit fingerprint. Photos whose fingerprints nearly match are the same picture saved again, resized or re-compressed.
- What is keptEach photo appears in one group, and exactly one file per group is kept: the oldest of exact copies, otherwise the biggest. Everything else is ticked, and you can change that.
- Moving copiesIn Chrome and Edge the finder can move the ticked copies into a “Duplicates (Diskshaper)” folder inside the one you chose, so you can check them before deleting. Other browsers cannot change files, so you get a list to download instead.
Check your whole drive
The Diskshaper app finds duplicate photos and footage across your whole computer, plus caches, game leftovers and old installers, and moves what you pick to the Trash.
