KDiskFree displays the available file devices (hard drive partitions, floppy and CD drives, USB sticks etc.) along with information on their capacity, free space, type and mount point. It also allows you to mount and unmount drives and view them in a file manager.
KDiskFree is similar to the KInfoCenter Partitions module, but takes up less screen space. It is useful if you want to keep a KDiskFree window available at all times.
