SpaceSniffer

SpaceSniffer is a freeware (donations are welcome) and portable tool application that lets you understand how folders and files are structured on your disks. By using a Treemap visualization layout, you have immediate perception of where big folders and files are placed on your devices. Treemap concept was invented by Prof. Ben Shneiderman, who kindly permitted the use of his concept into this tool.

Wow. Awesome program. It helped me find a lot of hidden and forgotten files that were taking up a lot of space. I highly recommend it if you are looking to free up disk space.
