Zero Assumption Disk Space Visualizer

Useless data will always pile up on your hard drive no matter how hard you try to prevent it. Zero Assumption Software's Disk Space Visualizer is not a standard disk cleaning tool. It's a small application that actually shows you what data is filling up all your disk space and if it's important or not.

The program is absolutely free and you can download the barely one Mb kit with no trouble. The installation process is a standard wizard that requires a few clicks without any questions asked.

There's not much interface to this software. All you get is a small window. First, you need to click the "open drive" button and select a partition. Then, the program will scan it and it will display a coloured chart of your free and used disk space on the main part of the window. Depending on how much free disk space you have or how large a folder is, their corresponding colored rectangles will be smaller or bigger. For example, if you have a freshly installed system and few things on your hard drive, the largest shape will represent your disk space, a smaller, but consistent one will be your Windows folder and so on.

You'll be able to see rectangles within rectangles if that folder has any subfolders. This doesn't stop here. You can navigate through the whole chart just like a normal explorer window. Double clicking a rectangle will show you a more detailed look about the content of the folder, all shaped according to size. You will find any piece of data represent here and if you spot something non critical, you can, of course, delete it just like in an explorer window.
