I think I'm correct in assuming that the iPod does not transfer files from its library to the PC it is connected to. So, in other words, if I reformatted my computer and put all of my music on my iPod, I would not be able to transfer that music back to the newly formatted computer, right? However, are there other programs that can perform this function? I have about fifty gigs of music on this computer and it is urgent that I reformat before the thing dies on me. Help.
