I purchased the Aerosoft A320/321 for FSX on Steam. Today I downloaded a Condor livery for the A320 and the read me instructions state "just drop the folder ''Texture.DAICU'' in the aerosoft A320X CFM folder located in '' SimObjects\Airplanes'' folder". But I cannot find the Aerosoft Airbus folders anywhere. They are not in Program Files (x86)>Steam>steamapps>common>FSX>SimOjects>Airplanes where all my other aircraft are located. I checked Onedrive and there is an Aerosoft folder there but it only contains Flight Plans and Fuel Planner folders. Does anyone know where I can find them?

Check the location where Steam installs your games, this can be different on systems depending on windows (and even on language). But the Steam interface can show you the path.

 

I can find the other Steam aircraft in: Program Files (x86)>Steam>steamapps>common>FSX>SimOjects>Airplanes . But the Aerosoft Airbus' are not there.

If its the same as P3D check your documents folder there maybe a Aerosoft folder in there.
