Made for a clear start
Choose your task, follow the numbered steps and review the result. You can hide instructions or turn off the startup walkthrough in Settings.
Privacy and practical limits
Recorded filenames, paths, hashes, drive identities and labels stay local. Camera input is used for QR scanning. Exported catalogues can contain private metadata.
Offline records describe the last completed scan. Hash matches are recorded evidence; reconnect and verify current originals before relying on copies.
Features in practice
The feature list describes the available tools. These examples explain how they support a practical workflow, what to review and where the limits matter.
Keep drive identities understandable
Stable drive identity, names, labels and QR labels help distinguish physical drives. Removing a saved catalogue does not erase the corresponding drive.
Refresh and compare recorded contents
Incremental scans, snapshots and change counts help identify added, changed or missing entries. Interrupted resume requires source checks and compatible access.
Review copy evidence and share a catalogue
Recorded duplicates, copy coverage, category summaries and supported exports help plan storage work. Only the relevant verified content evidence should be used to assess copies; metadata alone is not proof of identical contents.
Use the compatibility, access and limitation information on this page when choosing a workflow. Sample screenshots illustrate the app; their records and measured results are not a scan of your own Mac.
