MOBZHunt (64-bit)

MOBZHunt helps you figure out where all the free space on your hard disk went. It's extremely simple to use select a folder at the top, press the Open button and wait for MOBZHunt to do its thing. When done (you can press Cancel at any time) you will see a list of files and folders, each displaying the amount of space they occupy, including all subfolders. By clicking on the column headers in the right hand list, you can sort on name, size or date, which shows you at a glance which folders are disk hogs.
