DirSpace

This program offers the basics in locating resource-hogging folders on your computer, but it doesn't offer any file-management tools. DirSpace's utilitarian window lets you easily choose a hard disk or specific folder to scan, and the results include the folder name, number of files it contains, and the size. Although the presentation is simple, you can quickly sort results and export them in numerous formats. Options are limited, but we like the ability to flag folders exceeding a user-specified size, which made it even easier to spot oversized files. And purists will appreciate the two options for defining a megabyte: 1,048,576 or 1,000,000 bytes. Unlike similar programs, DirSpace doesn't let you delete folders or view the files within them, but you can right-click a folder to open it in Windows Explorer. Despite the lack of bells and whistles, this freeware utility makes it easy for any user to find those monster files, and you can't argue with the price.
