Windows only: Free space analysis utility SpaceMonger visualises hard drive usage with a drill-down treemap view of your file system so you can quickly identify wasted space. Using the application is easy—launch the executable, pick a drive to analyse, and then drill down through the treemap to identify the files that are wasting space. If this concept seems familiar to you, it's because we've featured many of these applications before. Previously mentioned apps like DriveSpacio, Windirstat, and Free Disk Analyzer all do the same thing with slightly different interfaces. This application is lightweight and contained in a single executable file, making it worth a look as another addition to your flash drive toolkit. SpaceMonger 1.4 is a free download for Windows only. The latest version isn't free, but you can still download the freeware version from their downloads page. Thanks, Nik Coley!
