Removed enemies?

[Alcoholocaust]

There is a folder called "character infected" in the game directory, I had a saved game before at a point near an alien coming near me..

Then I removed all the stuff in that folder and the aliens voice didn't come up and nor did the alien itself.. Does this affection make all those alien enemies dissapear now?

I was just wondering if it's possible to finish the game with that folder removed or does it not go well with some certain parts of the game?

The reason why I want to do this is because I'm going to write a walkthrough to the game and it would be a lot easier with no enemies, then I can explore all rooms and corridors much, much easier?
