Directory Hog

Directory Hog lets you quickly see how many folders and subfolders (along with their sizes) you have saved to a drive or directory on your computer.

The program displays the number of files found within each folder, the total size of the folders, and the size and name of the biggest file in each.

The tool's options let you exclude selected folders or, by default, any that take up less than 10 megabytes.

Directory Hog is perfect for figuring out which folders take up the most space on your hard drive, a tidbit you probably don't know off the top of your head.
