SpaceHog

Though it's light on tools and display options, this small program quickly and effectively calculates and reveals how much of your system resources a specified directory uses. The executable is compact and requires no installation, but it requires Java to run properly. You can't go wrong with SpaceHog's overly simple interface. Though it may lack pizzazz, it's very easy to use and understand. It's simple to browse for the directory you want to check, and the program automatically displays how large the directory and subdirectories are. After finishing a scan, SpaceHog generates a plain list of results. Unlike similar tools in its class, the program doesn't offer visualization features such as graphs and pie charts to show memory use. Also, it displays stats in kilobytes rather than megabytes and percentage measurements common to similar tools. Unfortunately, the program offers no printing or reporting tools, and you can't open or delete files directly from the program's interface. Although this freeware application delivers the basics well, it lacks a few bells and whistles that would make it a more solid choice.
