To show a pie chart of the computers contents click this button on the toolbar..
The Pie can be used to see what is using up you disk space.
It can be telescopically browsed.
Left click a folder to go into it. (ie. Down a level)
Left click the space surrounding the pie to Go Up a level.
It can also be used to view delete, and get properties of disk objects.
see also.. Pie Menu for further explanation of click functionality.
I also had fun with the colours etc. for the pie.
Look at the Change Colours Menu in the config menu for where to do this.
Use the filter to view only certain files in the pie chart.
