One Good Copy

Find duplicate folders and photos across all your drives, and see what fills them.

- Finds similar and duplicate folder trees: matching trees across disks, side by side.
- Finds photo families: RAWs, camera JPEGs, edits and resized exports. Never suggests deleting a RAW for its export.
- Space map and file tree explorer: what fills each drive, folder by folder, by type and age.
- Instant search: all files on all drives in about a second. Filter by type, age, camera, lens and more.
- Fast scans: metadata first, fingerprints only for media it cannot match otherwise.

Access: the snap reads only what the system lets it. Connect the extra access once after install:
sudo snap connect one-good-copy:removable-media
sudo snap connect one-good-copy:mount-observe
sudo snap connect one-good-copy:system-observe
Folders outside your home and removable media need classic confinement, which is not granted yet.
