I've run out of space on my external harddrive where I keep my backups (using CrashPlan) so I located the backups on the drive and deleted some old backups. I hoped to do so at least. I can't so right now they are just lying around in the trash can. They can't be deleted and I can't move them back to their orignial folder either. Some of the backups got deleted in the process but there are still six packages left. When trying to empty the trash can, I just get an error message saying: "The action cannot be done since "Applications is still in use" (freely translated from Danish). What can I do now?
