Hey everyone,
I tried searched for this but i kept recieving a server error so I decided to just post the question.
I recently installed Windows 7 on my computer and I rearranged my hard drive and got them all in order. On my old copy of Vista my music library was stored on my 1tb hard drive which was like drive L. Now my 1 tb hard drive is under drive D. I backed up everything including my iTunes so now it has all of these song files that it can't find. Is their anyway I can update it so it'll update and use my new drive letter? I don't want to go through and add them all again because then I would have to remake all of my playlists and I don't want to do that. Is their anyway to mass change the library to another drive letter?
Thanks in advance.
