Ive never really paid close attention to how much free space I have, because Ive always had plenty. I don't have any big programs, and Im am constantly doing maintenance. Deleting temp files etc. Now, all of a sudden Im down to 10% free space. Ive done disc clean up, but there isn't anything for me to clean. Only thing I can think of is maybe using system restore too many times. Or does that make a difference? Help!
