Good program for examining folder sizes in Windows

My hard drive was filling up at work, and I wasn't sure where all the big files were scattered.  I used the very excellent FolderSizes program, and it worked like a charm. It helps you find those 5GB directories you've forgotten about. There is just no way to figure it out in windows. Highly recommended.
