I was trying to reformat but it just installed over the last windows. The user files are still there but I can't delete the user. And my 160gb hard drive is now full.

. I spent my last $10 on a windows xp cd on craigslist and i ended up with just service pack 2. i have no access to a windows cd. is there any way i can go in and delete the biggest parts manually? I doubt there is any program that could help with this. Wish there was something that could clean up everything and leave windows like braind new. I have my stuff backed up on a flashdrive if there is.
