Find Which Folders Are Using All Your Disk Space With DarkMatter
DarkMatter is a free windows utility that analyses either your entire disk or just a selected directory and clearly displays which folders are consuming the most disk space.
The application allows you to quickly drill down to the problem folders, which may be nested many levels below the root directory.

This application is built using the .net 2.0 framework. If this is not installed on your computer you will need to download and install it from the Microsoft site. See the related links below for more information
To use the application run the executable file by double clicking on it.
The first screen you will see is a splash screen with a brief description of the application and how to use it.
Next select the folder or drive you want to analyze (you can also select UNC network paths)
To analyze the entire drive, select C: (or whatever drive you want)
To analyze the contents of a particular folder (e.g. C:\Windows) select the folder
Press OK and the application will start scanning the selected folders. This can take some time if there are a large number of files and folders or if you have selected a UNC network folder. You can stop and review the progress at any time by pressing the stop button.
When the analysis is complete or after you have stopped the scan, a tree will be loaded with details of exactly how much disk space each folder takes. The text in the tree is color coded, making it very easy to see which folders the largest. Each folder has the size of its entire contents printed after the folder name.
Once the folders are loaded you can alter the view and display the folder sorted by the number of files or folders they contain and you can choose to display the number of files or folders contained in each folder on the tree.
