analyze disk space usage

Our Rating: (Very Good)

SpaceSniffer analyzes a selected hard drive and presents you with a dynamic disk map that makes it easy to spot files and folder that take up most of your space. You can review the map in real-time while the application is scanning, and any changes made (e.g file deletions, renames, new files) during the scan are automatically reflected without the need to rescan. Other features include support for NTFS Alternate Data Streams, customizable chart colors, file filtering, folder zoom and more.
