Space Radar is a hard drive and memory space visualizer that allows interactive Sunburst and Treemap charting of the results.

Space Radar's interface has a more Mac look and lets you scan drives, folders, or memory, or load a DU file when you start. The same four options are always found across the top as well.

The first drive scan might take some time. When completed, it's a very nice-looking sunburst of your drive space with a breakdown of what's using the space in the top right. You can move your mouse anywhere in the sunburst to get details. You can click the icon in the top-right to switch to the treemapping view.

We were unable to get the memory scan to work, though the author has screenshots showing it working. Since we test safely in VMWare, we put this on our main computer and still had no luck, so we can't review that aspect of the program.

Windows, as you know, can give you drive and memory information, but it's pretty limited. Space Radar fills this gap by providing you with all the details you could need about your drive and memory use.
