I keep trying to update my iPod to iOS 5, and it keeps telling me I don't have enough free space on my computer. I put basically everything from my computer onto my external hard drive, I also tried moving everything in iTunes to a media folder. I also dont understand why it isn't updating and saving from my iPod. It's saying I dont have enough memory to update my iPod and keep the media that's on it.
How do I update my iPod and still keep everything that's on it, and how do I move everything in iTunes onto my external hard drive?
