XP has System Restore at "My Computer Properties". It doesn't cost that much space and you can disable it.

ThinkPad has some recovering stuff, right?
> What is this? I called ThinkPad today but the guy did not say anything about "recovering stuff". Maybe I will call tomorrow and hopefully talk to a different person.
You can also enable viewing hidden files to check again if you have done that.
> Do hidden files get added to the folder size? I think I have already set all hidden files visible. I checked all the folders under c: but nothing is big.
