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 naviagate and select how you want the data presented or saved.
