SpaceSniffer is a freeWare (or, better, donationWare) and portable tool application that gives you an idea of 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 situated on your devices. Treemap concept was invented by Prof. Ben Shneiderman, who kindly permitted the use of his concept into this tool.
Start a scan process and see the overall situation. Bigger are the elements on the view, bigger are folders and files on your disk. You need more detail on a big folder? Just single click on it. The selected element will be detailed with its content.
Need more and more detail? Keep selecting elements and they’ll discover their secrets to you. Need a larger view of a small folder? Then double click on it, and it’ll zoom to the full extent of the view.
If you need to understand why no more free space is left on the media, keep following bigger elements. Maybe you want to focus only on particular file types… ok. Just type the file type on the filter field (example: *.jpg) and press enter. The view will react and show you only JPEG files.
Want to know if you have old files? Type the condition in the filter field (example: >2years) and the view will react accordingly.
You can also filter on file size, file date and combine all filters
