Im running low on HDD space, and I think i found out why, I have over 40 gigs of music... So I moved it all to my external Harddrive and now that I have done that, when I go to at a folder it re-puts the music on my computer harddrive, how can I make it so that it just reads it straight from the external, rather than having to take up so much space. I also have 3 movies I bought off of iTunes, is there a way I can move those off as well. Thanks!!!
