Title might not be specific enough, here's what I want to do. I want to completely wipe my MBP and clean install everything. I can individually backup everything I need, except I'm confused by iTunes. My large library is about half iTunes purchased content (which I don't need to backup because it's in iCloud attached to my account). I do want to backup all my non-itunes purchased media. Is there an easy way to separate these files by type? what is the bast way to backup non-itunes purchased media? Thanks.
