FullDisk

FullDisk lets you view your hard disk contents
on a tree-by-tree basis. FullDisk gives you a
Tree to navigate among your local or network
drives and their folders.

Select a drive or
folder and FullDisk computes the size of that
branch and shows you the results on a per-folder
basis using a colored list box of sub-directories.
Also, the data is shown as a color pie chart.
Double clicking on the pie chart or the list box
navigates down the tree. Menu picks, popup-menu
and the Tree help you navigate and select how
you want the data presented or saved.
