Form over function

See what's taking up space on your computer with this program's weird graphs.

After months or years of use, it's not uncommon for computers to become cluttered with unneeded and duplicate files. This not only takes up space that could be used to store useful data, but also contributes to poor performance. Disk Space Fan allows users to see exactly what's taking up room on their computers and eliminates the space-wasters. Although the program works just fine, it's definitely not the most intuitive we've ever seen.

The main problem that we encountered with Disk Space Fan is that it tries a little too hard to be cool, favoring sleek graphics over useful descriptions. We're all for an uncluttered interface, but this program takes it a little too far. The program opens with a list of available disks down the left side, and clicking on each one displays a pie chart showing the amount of full and free disk space. Users can then have the program scan each disk and analyze its contents. This is where the program really puts form over function, displaying the results in what the program calls a "ringschart." A central circle represents the directory, with a series of nested rings representing each level in the directory. Users can click on each ring to display a new ringschart that drills down deeper into the directory. Yes, it looks cool, but it just didn't seem like a very efficient, easy-to-process way to display the information. The online Help file is adequate, even though it opens in Internet Explorer whether you want it to or not. In the end, Disk Space Fan wasn't exactly difficult to use, but we felt like we had to spend too much time trying to figure out how to navigate the interface and interpret the graphs.

Disk Space Fan installs politely but leaves a folder behind upon removal. We recommend this program with reservations.
