SUMMARY: Find out why your hard drive is running out of space by scanning it with TreeSize Free.

TreeSize Free for Windows can help you determine where hard drive space is going by displaying a directory tree of each folder on a drive with the space used.

File size can be reported in gigabytes, megabytes, kilobytes, or a combination.

Other features include sorting files and folders by name or size. Files can be filtered by extension, so you can see how much room is taken up by movies or MP3s, for example. Examined folders can be opened in Explorer. You can print a report of the software's findings. The gradient colors used for the chart can be changed.
