# Why did an app fail to move, and what should I do?

Click the failed row — Storage Studio shows the reason in plain English and what to do next. Common causes:

- the app was opened during the move — quit it and try again;
- the fast drive was disconnected or is full;
- the copy didn't match the original, so the move was rolled back;
- something else is now at the app's location and Storage Studio won't overwrite it.

Whatever the reason, your original app is kept safe.
