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.
