Disk is a very useful device to a computer to save data file. For that, is much needed
to have a program that has a capability to represent, navigate, and operate that files. There are
many computer programs that used to present, navigate, and operate disk files in text form with a
lot of facilities, but only a few programs that can represent files in a graphic form and have
special feature, like capability to find the biggest files that use disk space. This capability is very
useful in disk file management.
This software use split screen system method and tree map algorithm. Split screen system is
used to navigate, where the monitor screen divided into two parts to visualize files in a disk, the
small part (map navigator) visualize the whole content of a drive or directory and the big part
visualize the detail of a part according to focus box in the map navigator. A mouse can move focus
box in the map navigator and the box size is the comparison between map navigator sizes with
map view size. Tree map algorithm is used to calculate the size of box picture of the represented
file. This algorithm needs a complete tree structure from a drive or directory that will be painted.
The software to make this windows based program is Borland Delphi 5.0.
