ref the IL-2 FAQ...
"Where do I put downloaded missions in order to play them?
Into the 'Forgotten Battles/Missions/Single' folder if it's a single mission. Into the 'Forgotten Battles/Missions/Net/coop' folder for coop missions and into 'Forgotten Battles/Missions/Net/coop' for dogfight missions.
Missions you played online will be saved in 'Il2 Sturmovik/Missions/Net/cache' and you can reuse them if you like."
I can locate this files, but how can I refly or load them in to the mission builder???
