How can I find out what files are taking up the most space on my hard drive?

Episode 1303 (1:49:42)

Chuck from Riverside, CA

Chuck says his hard drive is filling up, and he has no way of finding and deleting the files that are using up the most space. Leo recommends using a free program called WinDirStat, which will give him a visualization of the files taking up space. It will also give him the option to delete files. Chuck should just make sure to empty the Recycle Bin after he deletes files.
