I have a QR archive which QR says is bad. I selected the option to recover to a new archive. When recovering, does QR move data from the old to new archive or does it copy those data?

The reason I ask is: There is only 71 GB of free space remaining on the QR archive volume but the archive itself is 398 GB. Clearly there is not enough room on the archive volume to recover much if data are copied instead of moved to the new archive.

So, copy or move? Do I need to use yet another volume to create the recovered archive or will the present volume do?
