If they are used as part of the snapshot and you want to revert to that. For example, if you take a snapshot of a live VM, you'll have a Α.sav file. If you take another one at a later time, you'll have a B.sav. If you want to revert state A, you'll still need the first A.sav.AllenL wrote:It was mentioned above that the .sav files are created during snapshots and must not be deleted.
Since you merged them, I don't think you do, but I would simply quit VM and VirtualBox and move the Snapshots directory somewhere else. If it works, you know you can delete them.
