I use Mail.app for my email, and I've had to restore from backups before. Not knowing much about such things, I just copied my backup folders onto the hard drive, and restored what I could by just tinkering with mail to see if I could get my old messages back. So now I'm reorganizing my stuff, and finding that I have three copies of practically every mailbox. One's in the normal place (Library/Mail/Mailboxes), one's in backup/Mail/Mailboxes, and one's in backup/backup/Mail/Mailboxes (!). The normal place one is the only one that's organized how Mail currently shows my organization. So my question is: is it safe to toss the old ones? (They're each at a half a gb...) Thanks very much!
