I would like to install a Mod, but find the terminology confusing.
The SE4 Gold manual talks of the "Main Directory" on page 81 but gives table 1 of the "Default Directory". 
Are they the same? Different? If so, how?  
 
  
I've been a Mac user for 20 years and just "coverted" to the P4 platform. So I am in grade school in all this (maybe even kindergarden...).  
 
     
  
So, I need help from the ground up.
