From a mess of copies to one clear picture
Know where the best version of every file is — connected or not.
One uncomplicated journey to catalogue, compare and sync every drive, folder and file you own. Duplicates and corrupt copies are flagged across all of them, plugged in or in a drawer, and nothing is moved or deleted without your approval.
- Finds bit-rot, and the healthy copy A file whose contents changed while its size and date did not is flagged, and Whichdisk points at an intact copy on another drive.
- One scan, every answer The same catalogue serves search, duplicates, folder comparison and sync. Drives can stay unplugged; the catalogue remembers them.
- Nothing is deleted without a safety copy Every sync and clean-up is previewed first, and anything it would remove or overwrite is copied to a folder you choose, so you can undo it.
