You need to clean up your hard drive.
It is sometimes difficult to figure out what is consuming all of your hard drive space. You could spend hours opening up each folder and right-clicking to properties, or you could let this little application do the work. WinDirStat will scan each folder on your computer (or a specific drive or folder) and present you with a beautifully formatted list and interactive graphical representation of every file on your hard drive. You can then drill down, select individual folders or files, and find out very quickly what is using the most space.
I have found it very easy to use. It does not take long to scan the hard drive. The graphic allows you to visualize all the files on your hard drive and quickly eliminate any large files. I recommend it to anyone who is trying to cut down on hard drive clutter.
