Moving between 2 PCs

I play on 3 different PCs over the course of a couple of weeks and have installed this on all three of them. I have tried without any luck moving the DIRs between the different PCs to keep my zone info etc current on the computer I will be using. However, it seems I am not getting the required files all moved, each PC I play on is acting like its own separate
install. What directories need to be copied to move this between PCs?
