So I have 42 gigs worth of apps and I honestly have NO idea where it's all coming from. I have no apps from itunes, and I don't have any games installed on my computer, except for Sims 3. I can't tell what exactly is causing so much space to be taken up. The only other apps I have are simple apps that only take a few megabytes, nothing that takes up gigs. Even total there's no way it's 42 gigs, I'd be surprised if it's even over 3-4 gigs.
