Although at first glance the display can look a little cluttered with its assortment of rectangles, it turns out that this is actually a very effective way of judging what's on your hard drive. Clicking or double-clicking allows users to zoom in and view more detail about the contents of each folder. The program can also highlight groups of rectangles that make up a larger segment it drew a white outline around the group of rectangles that represented the items in our program files.
A medium-size rectangle represented our application data, for example, and a smaller one represented our desktop. The result is a mess of rectangles of different sizes that represent files and folders. Users simply select the drive they want to scan, and SpaceSniffer sets to work analyzing its contents. The program's interface is simple and intuitive. Although the results can be a bit overwhelming at times, we found it to be an effective way to view exactly what is taking up space on our computer. SpaceSniffer is a useful program that provides users with a graphical representation of the contents of their hard drives.
