File Type 2Flight Simulator Scenery File
.BGL File Association 2
Data file used by Microsoft Flight Simulator, a flight simulation game; contains scenery data for flying locations and airports; small locations require a single BGL file, while more complex locations and airports may use multiple BGL files.
BGL files included with Flight Simulator should not be modified. However, custom BGL files can be created to create custom flying location and airports. These files should be saved in the following directory:
Microsoft Flight Simulator X\AddOn Scenery\scenery
They can also be stored in a custom directory within the main Flight Simulator folder, such as the directory below:
Microsoft Flight Simulator X\Custom\scenery
Custom BGL files can be created and compiled using third-party programs. Once a custom BGL files is placed in the appropriate directory, it will be available in the game.
