Main Directory and Default Directory?

Question 1: The name of the mod is TGEmod10 and I assume that I would repace "None" with the TGEmod10 Y/N?

It is a simple mod, just changing the mineral/organic/radioactive production of facilities and the availability of the destroyer at game start.

Question 2: If I play a different game, do I have to change the path back to "None" In other words, does the computer "know" which mod is attached to which game or do I have to do it manually whenever I switch games.

1) Probably. The path refers to where the mod is, and that is not nessesarily the mod's name.

2) Yes. If you try to load a savegame using the wrong mod, SE4 will may complain that the files are different, and that someone is probably trying to cheat.
