SpaceMonger is a unique visual tool that can be used to see just how the space on your hard drive is being used in real-time. The program does this visually. It looks at individual files and folders. It then creates a box for each one on the screen. The boxes are colored and labeled according to the files and folders. The size of the boxes is proportional to the total amount of space they occupy on the drive. This provides a fast way to assess whether a directory or program is getting out of control. Users can navigate around the program to see disk usage at different levels of the file structure.
