You have a HUGE hard disk on your Windows PC, and something is using up all of your space!
What can you do to find out what it is?

TreeSize Free V1.7.9
TreeSize Free tells you where precious space has gone to. TreeSize Free can be started from the context menu of a folder or drive and shows you the size of this folder, including its subfolders. You can expand this folder in Explorer-like style and you will see the size of every subfolder. Scanning is done in a thread, so you can already see results while TreeSize Free is working. The space, which is wasted by the file system can be displayed and the results can be printed in a report. TreeSize Free is freeware for Windows 9x/NT/2000/XP.

If you are looking for a more robust product, complete with graphs, tables, and pie charts, they sell a Pro version. But for personal use, the TreeSize Free version is all you need.
