Man your hard to understand. Hay man XP hidden files all over the place if your telling me you got a 5 gig partion well that's you problem make it bigger say 10 gig. Remember the trash can takes up 10% even when empty that's 500 meg right there. Ya can figure a bunch more of hidden files I've heard almost a gig could be on a xp machine according to the guys at windows annoyances.com. It reserves space all over the place....
