Each folder is tied into a specific character. If you use the same Chief all the time, he will always have whichever file you used. I have no idea which folder goes with which individual, so I can't help there. All I can suggest at this point is experimentation.
Also don't forget the 'Fix' pack, that changes the 'Ahead Slow' so it only whispers while Silent Running.
