I have FSX Deluxe with SP1.
When flyawaysimulations.com downloads have "Missions" folders (or subfolders with categories), I know what to do. Also, when they they have scenery and texture folders (for placement in Addon Scenery and activated after FSX is booted at Settings\Scenery Library\Add Area), that's OK. An example of a well organized download is Back Country.
BUT- some downlooads come with only a few files (e.g., a .bgl, an Adobe Photoshop Plugin, and some .JPEGs). For example, see Belize Atols.
Is there any general instruction you can vector me to that might provide info on installing this stuff?
