Why does an app move say there is already a copy on the drive?
Short answer: A leftover copy from an earlier unfinished app move is already on the drive. Run Verify Setup, discard unfinished moves on the app moves row, then try again.
A copy of the app is already sitting on your drive — usually left behind by an earlier app move that didn't finish. Storage Studio won't overwrite it automatically, because it can't be certain which copy you want.
### What to do 1. Run Verify Setup from the More menu. 2. On the app moves row, choose Discard unfinished moves. This removes partial copies Storage Studio itself left behind; your apps in Applications are untouched. 3. Try the move again.
