Hi Penguinpaul, thanks for replying!

Unfortunately I use XP, and I can't copy all the music to my iPod because it's only a 1GB Shuffle and my library is 10x bigger than the available space.

I have noticed that I can still open my old copy of iTunes via Programs on what is now the D: drive. However when the library window opens, it's empty (of music AND playlists). Now whilst I hoped that opening iTunes from D: (I haven't yet installed it on C:, and would even be happy to use the copy on D: if it's possible and just create a desktop shortcut) would preserve the playlist structure and links, I'm guessing that the reason it hasn't is because it's looking for links to the music on the C: drive, when of course the designation of that drive has now changed to D:.

What I don't know is how to deal with it - any ideas?

Thanks,

Rich
