# How does Storage Studio make sure a moved app copied correctly?

Before it replaces anything, Storage Studio checks that the copy on your fast drive matches the original — every file present and identical — and that macOS still sees the app as intact and correctly signed. Only then does it put the shortcut in place.

If any check fails, it rolls back: the copy is discarded, the original is kept, and you're told "nothing was deleted — the original is safe". We don't publish every detail of the checks, but the promise is that an unverified copy never replaces your app.
