Being a homely moron, I certainly don't freely offer advice, but as to your
problem with BookReader, all (both) my books are on my SRAM card. I
duplicated the necessary file structure on my SRAM card and now when I tap
the World or Documents ICON, it shows all apps or docs on the B: or C: drive
in that particular directory. And if they are apps in the world or main or
whatever directory, they also show up on the launcher.
