Finding things in Finder · Opening and using moved files
Can I keep using Finder and my files while Storage Studio is moving a folder?
Short answer: Yes. Moves copy and check first and only replace the original at the end, so your files stay put until the copy is complete. Leave the folder being moved alone until it finishes; you can hide the progress sheet meanwhile.
Yes — keep working. A move copies the folder to the drive first, checks the copy, and only then replaces the original, so your files stay exactly where they are until the copy is complete.
For the folder actually being moved, it's best to leave it alone until it finishes. Before a move starts, Storage Studio checks which apps are using files in that folder and offers to ask them to quit; a folder an app is busy writing to can wait for Move when closed instead.
You can hide the progress sheet and the move carries on in the background. If you quit and relaunch mid-move, Storage Studio picks it back up.
