Extracted Cat files

[greyhawk 8]

I have actually axtracted all the cat files, except 2 which says it is wrong. I did make a copy of all the cat files but the question is after I have extracted them and edited them where do I put them. I am running new strick fighter 2, windows 7. In the same respect with mission files. should the msn files go directly into the mission folder. I notice I have folders in them called combat missions, training missions and other missions. Should the msn files actually go directly into the mission folder of saved games/thirdwired/strickfightervietnam/missions?
