Filerev vs. SpaceSniffer Comparison Chart

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 an immediate perception of where big folders and files are placed on your devices. The Treemap concept was invented by Prof. Ben Shneiderman, who kindly permitted the use of his concept in this tool. Start a scan process and see the overall situation. The bigger the elements on the view, the bigger are folders and files on your disk. Do you need more detail on a big folder? Just single click on it. The selected element will be detailed with its content. If you need to understand why no more free space is left on media, keep following bigger elements. Maybe you want to focus only on particular file types. Just type the file type on the filter field and press enter. The view will react and show you only JPEG files.
