iTunes library location automatically reset and library "lost"
I'm working on a Windows PC. Long ago I pointed my iTunes library to an external drive because my local drive was running out of space. I recently moved what I thought was old/duplicate content off my local drive to a new backup on an external drive. When I next opened iTunes all my playlists and most content was gone so I cnecked my preferences and somehow (during an iTunes update?), my library was pointed back to my local drive. I still have all my content, but it's in multiple external drive backups. I guess my iPod has the most current playlists and some content, but I have no ides how to recreate my library from my iPod and all the external drive backups. Also what's up with iTunes changing my library location back to my local drive??
