Hi again. Sorry, I guess I didn't answer the question before - I checked the C drive - it is the only hard drive that appears in "My Computer." See the funny thing is, I feel like I've deleted everything non-essential. I really don't have very much stuff. And yet my computer is still completely full. I even got extra RAM for it a few years ago. It is pretty old, I suppose. I think I'm going to try taking all my music and word documents off and reformatting it (again). Thank you all so much for all your help!
