HD showing too many gigs
hi i just got a new system totally up and running and noticed that my hard drive is showing way too much used-space. i have maybe 50gigs of media and then just a handful of programs that ive installed but it says my capacity is at 153G.
when you use explorer and add up everything in the c drive it comes to what it should, 50 some odd gigs. what could this other 100 gigs be from? could it be my hard drive is bad and it just appears full? virus? norton says im clean. TIA
