I just bought one of the new 4th generation iPod Nanos (8G). It's my first iPod and I hooked it up to my iBook as soon as I got it. It automatically opened up my iTunes, but I wasn't entirely sure how to put my music onto the Nano using iTunes. So I opened up XFolders file manager and transferred all my music to my Nano using that, just like I had done for my old iAudio MP3 player. The files transferred and once I was done charging my Nano, I turned it on and it said there wasn't any music on it. According to iTunes, I had almost 1GB of 'other' files on it, which I assumed was the music. I figured I must have to use iTunes to transfer my songs, so I hooked the Nano back up and figured out how to sync my music. That worked fine and the Nano said I had music on it. Of course, then I had twice as many files on the Nano, since there was 2 copies of each song. According to iTunes, I had almost 1GB of 'other' and almost 1GB of 'audio'. So I next went back to XFolders and deleted the files that I had previously transferred using the file manager. According to the XFolders, the files were gone from my Nano. But, according to both my Nano and iTunes, I still have almost 1GB of 'other' files on it. So I guess those files were never actually removed? How do I go about removing them?
