Actually, I just figured it out. You have to enable the iPod to be used as a hard drive or set it to "manual" instead of "automatic" for file updates, and then it appears as a drive under "my computer" in Windows, and then just copy and paste the files.

Unfortunately, it doesn't store them on the iPod in any discernable order, so finding and copying what I want is going to involve some work. Maybe I can use the search function for Windows.

Also, I said I had forty gig. I don't. I have twenty.
