I bought my ps3 last Christmas and its 80 gig. When I check how much free space on my HDD it says only 55 gig. How did that happen? So far, I’ve downloaded 5 wallpapers, 10 songs, 3 game demos, 2 game, and Playstation home. Can someone explain to me what apps took that much of space? thanks

I have 76 % free space on my computer . Does screensavers and such take up much space or make my computer run slower ? I have downloaded a LOT of different screensavers .
