I have 2 x 1TB WD External Hard drives which hold all my audio/video content. One of these is full and this is the one that is located in the iTunes Music Folder Location. If I change this path to a path on the other drive which has space, is it going to mess up what I already have in my tunes library? I have keep iTunes organised and copy to iTunes music folder both unticked. My problem is when I'm downloading new content from iTunes, I'm going to run into issues as there's no more room!
