Data Transfers · Copy, Move and Sync
Can I undo a transfer or a sync?
Short answer: No single undo. Delete unwanted copies after a Copy; run a Move the other way to bring files back. Files a sync removed or replaced don't go to your Mac's Trash — check the cloud service's own trash. Dry-run first.
There's no single undo button, so how you reverse it depends on the operation:
- Copy — just delete the copies at the destination if you don't want them.
- Move — run a Move in the opposite direction to bring the files back.
- Sync — files a sync deleted or replaced at the destination aren't put in your Mac's Trash. If the destination is a cloud account, check that service's own trash or version history, if it has one.
That's why a Dry run is worth doing before the first real run of any Sync or Move.
