I dragged a group (about 20K text files, so less than 2 Gb) from a database (about 36Gb) to another one, when the rainbow wheel appeared, freezing DT and not going on even after many minutes.
So I made a force quit.
Now I’m not able to open the Database where the original files are stored: the rainbow wheel appears and DT freezes and doesn’t respond, even after many minutes.
The bar of the Opening Database stays still, empty and doesn’t go on.
I also copied and pasted the Database to another location and tried to open it as a new one, but nothing.
I also tried to recover an old version from TimeMachine, but it keeps saying I haven’t enough disk space (but the Database is 36Gb, and I have 96Gb of free space), so I’m not able to recover it.
The Database is synced via iCloud Kit.
I can open all the other Databases without any problem.
How do I fix it?
