Sorry if this is a dumb question.
I'm clearing out my hard drive and ran Omni Disk Sweeper, which shows a bunch of files in folders named Volumes > Firewire 1 > Documents > iTunes>, Volumes > Firewire 2 Documents > iTunes>, Volumes > Firewire 3 Documents > iTunes>.
The drive Omni is referring to is my external FW drive, but these files show up when the drive isn't attached. I can't find any of the files via the Finder, and I don't really understand why Omni finds Volumes that aren't mounted. Are these files (according to Omni, 2 gigs of them) actually on my computer?
