TreeSize

No matter how large is your hard drive, there will come the moment when there will be no available space for new software and files. To find out where the space has gone to, you can browse the disk and discover hidden 'treasures', such as long-forgotten MP3 archives, manually or use TreeSize.
TreeSize is a smart program that scans your logical drives (including removable media) and tells you the location of huge files or large folders. The program's features can be accessed through the context menu that is available in any folder or file on the system as well as the standard method - running the program from the Start menu shortcuts.
The tool lets you scan files and present the results in an easy-to-understand form. You can generate reports and print out information on how much space is wasted by the system. One of the most interesting features is the ability to assess how much space a certain folder would take up on a CD. Try this tool today and clean up your hard drive!

Every hard disk is too small if you just wait long enough. TreeSize tells you where precious space has gone to. TreeSize can be started from the context menu of a folder or drive and shows you the size of this folder, including its subfolders. Each folder can be expanded in Explorer-like style to see the size of its subfolders. Scanning is done in a thread, so you can already see results while TreeSize is working. The space, which is wasted by the file system can be displayed and the results can be printed in a report.
