Thank you Klaus_Doldinger & Nikbear for your complete and clear reply and comments. After reading your posts, I just went to check those famous folder and I discoverd that they were all empy except of course the 1.....It never crossed my mind to check them. Like you say, so many modders always make their work JSGME ready....Anyway All clear.
