Hi, folks. Relatively new user of an iPod here (Touch, 64 GB). I recently had a problem with an old computer crashing. It was old, about ten years old, so I wasn't surprised. However, it did raise my awareness about backing everything up. So now I am wondering, before this computer dies, which has iTunes on it, how do I back it up? I would hate to lose all the music I have put there. I am considering purchasing a USB Flash drive or even an external hard drive. What file do I have to copy and paste over? And is this file easy to find through Windows Explorer? By default, is it in a particular folder (I assume in the "Program Files" folder)?
