Uhh, okay let me tell you what I actually did. I got an IAF MiG 23 Grey zip from CombatAce, looked up on YouTube, it was compatible with the Europe DLC, I made a copy in the same folder of the SF2 Europe, got its folder Saved Games, opened the folder named objects. Now two folders are there, one is aircraft and one is ground vehicles. I pasted the MiG 23 file in the aircraft folder and it didn't work. I don't think I saw a ModsFolder on my search, can I make one?
