I haven't found a solution to this... I'm trying to back up my misic library onto an external hd. I already have the backup copy there, but it's been a while since I updated it. I have a lot of things that I want to keep on the external that I've deleted out of my iTunes library. Also, obviously, there are new albums that I have yet to copy over. I tried just dragging all the artist files over to the iTunes folder on my external and I got the message "there are folders with this name already in this location; do you want to replace them?" This is where the flaw is: For example, I have an old Beck B-sides album I want only on the external, and I just downloaded Guero, his new album. Thus, if I elect to replace the folder, the B-sides album will be deleted. Also, if I elect to not replace it, Guero won't be backed up. The only solution to this, I think, would be to expand all the folders before copying them over. Considering I have 60 gigs of music and hundreds of attists with new albums, I really don't want to have to do this. Apple really needs to fix this problem; it seems as if it would be easy for the copy process to include a scan within folders, and a subsequent addition of new files. This is extremely difficult to explain, so let me know if this doesn't make sense.
