The more we use the computer, the more our hard disk gets filled with useless stuff like junk files, temp files, old song files etc. WinDirStat is a free program that gives you a visual representation of your hard disk usage. It indexes the hard drive and creates a visual map of each file and also helps you in deleting the file that you don’t need.

It uses tree maps to represent each file as a visual rectangle so you can visualize file distribution across the drive. All the files are coded with a specific and color and you can click on them to reveal file name and even open it in Explorer, copy the path, delete the file. You can also view the folder organization in a drill down interface and get an indication on how large it is. The most noticeable feature is the visual representation of the hard drive with a lots of colored rectangles representation lot of different types of files.

It is a nice software which will allow you to see which is occupying how much space on the hard drive. It is a freeware and works with Windows 2000/XP/2003/Vista.
