Disk Space Fan is a free disk space usage checker offering a cool look on the graphics while on the other hand it manages to provide a fast scan. The program has both the combination of speed and sweet appearance packaged in one place.
When it’s done the scan, you’ll see right on the left panel the list of the folders and files that are responsible for the biggest disk space usage on the scanned drive. The main window itself contains slices representing the whole files and folders. The bigger the slice, the bigger the disk consumption. You can click each slice to analyze further.
Additionally, the application also features a custom folder scanning by which you can select any folder of your choice to be scanned individually, which is useful to narrow down your investigation when you know exactly which part of a drive that contains files with huge sizes.
Disk Space Fan is a freeware and designed to work for Windows 7, Vista and XP. It can handle either the 32-bit or 64-bit version. To make sure that you always get the latest update, download the program from the developer’s website.
