OK, what I did awhile ago was this: I took screenshots of the default folder structure. Then I illustrated how some folders could be added due to installations. I showed how some folders would be added to geometries, characters, props, textures, etc. The key here is the ability to show screenshots of whatever state you're illustrating. That isn't easy unless you have screenshots of the default setup, then make screenshots for any changes you wish to illustrate. I think I may have those screenshots still around...but am not sure. I got to the point where I stopped trying to save stuff to CD and finally just fdisked my drives so I could regain control of my computer. (After the virus I got.)
