You can now define a custom user folder by adding your location to the field: <[string8][extra_user_folder]> located within the main.mcf file. The location can be defined by placing it within the brackets of the command and saved.
For defining a custom scenery location the location must contain the sub-folder “scenery”. This will give you the ability to place your custom scenery in a location other than the documents folder located on the root drive. This will allow for Aerofly FS2 to scan for any image files in that location.
