My user account login was corrupted so I had to rebuild it. To keep the paths the same I first created a "Temp" profile, copied everything across, deleted my regular account, then rebuilt it. When I started iTunes, I checked the size of the itl and xml files and they were smaller. I copied the ones from my previous login from a backup, and after running iTunes again they were recreated, and again they were smaller. Does anyone know why this happens? I haven't made any changes to iTunes, I just opened and closed it. And why is it smaller? ( I can't remember by how much, probably around 1 kb or so). Thanks!
