Linux Tree

Does anyone know where I can find an online diagram of the complete opensuse Linux Directory tree please. I need to present some very basic selfrun online training to a windows group about the linux Directory Structure for preparation to cut them over in April and can't find one anywhere. I've at least talked them into using opensuse to start with, thanks to the UK Linux Format bringing out a "5cd Special Issue" plus Novell being involved with SuSE. thanks in advance scsijon
