I am trying to copy over Swat3 using Easy CD creator using the instructions provided on this website...but one thing just confused me...changing the file attributes from read only to archive...do you know what files they are talking about...http://www.gamecopyworld.com/ is the website I was looking at and that was the directions...what are they talking about and how do I do it!!!
