DriveSort

When you're running out of space on your hard drive, it's time to delete any unwanted files that are taking up that useful space.

DriveSort is a free application for Windows that allows you to figure out which files are taking up the most amount of space within a directory or hard drive. That makes it easier to then access them and delete them if you don't need them.

Using it is simple: just select the directory or drive that you want to analyze, and hit the Go! button to start the scan.

DriveSort also allows you to limit your search to recently created files.
