FlexSize Express gives you a visual perspective about the way storage is distributed in your hard drive, removable drive or even in any folder. It performs a fast folder system analysis and then displays a list with a graphic bar that shows the percentage of total room taken by each folder and file. As the program has support for profiles, you can create a few of them and assign different drives and folders for each one.
The results can be exported to several formats, such as HTML, CSV and TXT, but it can't be saved on the hard drive. Also, I missed the possibility of creating graphical pie charts, which are far more visually attractive and self-explaining than just a simple colored bar.
FlexSize Express analyzes your disks, folders and removable devices for a better storage distribution.
