:Feet On Couch - there is the initial downloaded file that has the books stacked on top of each other.
Exploring that shows nameofgame.part01, ....part02, .part03, etc.
Exploring the first one of those (.part01) shows a .iso file that is also represented by a stack of books, and described as a winrar archive. At that point I need to extract to see whats in there.
You can extract the contents of a .iso file with winrar, if you don't want to mount it with like daemon tools or alcohol, to see the contents.
