# How does Storage Studio make sure a move doesn't lose my files?

Every move copies first and only removes the original once the copy has been checked. If the copy is materially smaller than the source, the move fails and your original stays exactly where it was.

Other safeguards:

- **Cleanup on failure** — a move that fails partway removes the incomplete copy from the drive, never the original.
- **Interruptions are resumed** — if the app quits, your Mac shuts down or the drive is unplugged mid-copy, the next launch finishes the move cleanly or puts things back.
- **A shortcut is left behind**, so apps and Finder still find the files.
- **Space-efficient files stay efficient** on the drive instead of growing to full size.
