A problem I have no idea how to fix.

Ok, so basically I've partition my hard drive so that I have 30gigs on ubuntu and 30 on Windows. For the past few days I've been super board so I downloaded tons of games and software. What can I do to clean up my hard drive and find all the old folders left behind from games and such?

Assuming you've installed everything through Synaptic, you can uninstall them there. Remnants can be found in your home folder. Make sure to select "show hidden files" in Nautilus.

sudo apt-get autoremove && sudo apt-get clean

Will clean out unused and archived packages.
