Why does it say there isn't enough room on my fast drive before a move starts?
Short answer: Storage Studio checks there's room for the whole item plus a safety margin before it starts. Free space on the drive or choose something smaller.
Before moving anything, Storage Studio checks that your drive has room for the whole item plus a safety margin. If it doesn't, the move never starts — so there's no chance of a half-finished copy.
### What to do - Free space on the drive, or move something smaller first. - Check the drive's free space in Finder (select it and press ⌘I). - If you regularly hit this, a larger drive is the real fix.
