The short version
- Copy leaves the source completely untouched — the safest default if you're unsure
- Move only deletes the source after the destination confirms a complete, verified upload — never before
- A failed or interrupted move never deletes anything — the source is only removed on confirmed success
In practice
- Choose copy or move when you start a transfer.
- Copy: source stays, a new copy is written to the destination.
- Move: source is deleted only after the destination confirms the upload succeeded.
FAQ
What happens if a move fails partway through?
Nothing is deleted. The source is only removed after a verified, complete upload — a failure leaves the original exactly where it was.
Can I undo a move?
Not automatically — once the source is deleted (post-verification), it's gone from the source location. If you're unsure, use copy and delete the original yourself once you've confirmed everything landed correctly.
