Also - check to see if your school offers you filespace online ... a lot of schools do that (mine does). Gmail usually works, but it still might be worth it to get a flash drive - they are so easy. And you can usually get a 2GB memory stick for $20 (which is PLENTY of space for your purposes).
I think I'm gonna use UCfilespace, maybe gmail, and my flash drive ... may sound paranoid, but my hard drive just died (and I had it replaced) a few months ago, so ... losing everything is a reality to me, and I don't want that to happen in law school!
