rootfs is running out of space fast

edit

I just start using Fedora again after about 2 years. I just did a fresh install and only after two days of using it I was slapped with a low space error. I thought maybe it was a bad install so I re-installed Fedora 16 and already after a few hours it is jumping back up quickly. When I run the df -h command this is what I get:

Is there anyway to clear it out or remount to another drive... anything? I don't want to have to re-install my system every other day.
