Thank you so much for explaining all this to me. I was afraid the files were hidden somewhere in the system. It is good to know the game is being saved while I'm playing though. I look forward to the possibility of installing, or at least saving, to an external SD. I'll also search for backup methods, but if they involve rooting or hacking, I don't think I want to go that route.
I know many Android games run the same way as VF, and I risk losing data with updates and such with them too, but the VF peeps seem so real. Losing them would be a virtual "disaster." LOL
