I'm trying to free up space on my PowerBook so I have been beginning to think about moving some of my less listened to music to my external HD. Is there an easy way to do this and still keep the songs in the library, even though I know they will get the little "can't find file" exlamation point when I am on the road? Also, is there any problem with moving and using big apps like iDVD and GarageBand on the external HD? Thanks!!
