SpaceSniffer – Disk Analyzer

Space Sniffer - Freeware tool to visualize disk usage

SpaceSniffer is a free and portable application that will scan a drive and give you a visual treemap of the contents on that drive. This is useful for the technician who is trying to clean up data on a system, or is looking to delete/move data from a full partition to another with more space. What’s nice about this program is that you can easily analyze what files are taking up the most space, in a visual manner, and then use the interface to dig deeper into a directory or file.

SpaceSniffer allows you to modify your searches in many ways. You can look for specific types of files, such as .doc, or can look for older files by using a condition such as “2years.” The main menu shows a high level view of your data breakdown, and by clicking on a section you can drill down to see more files and how much space each individual file is taking up. You can even navigate the interface while a scan is in process.

At first glance the layout of your data in a visual manner may seem cluttered or bit confusing, but you quickly get used to it, and the visual aspect helps you hone down unnecessary files with ease.
