How to recover the original vehicles_airport.bgl that comes with P3Dv4.5?

[edwardpat]

Hi:
I have two very similar "vehicles_airport" files in my "<Main P3D folder>\scenery\global\scenery" directory, one is named "vehicles_airport.bgl" and the other one is named "vehicles_airport.gsx". I have GSX Level 2 installed, and want to know which one of these two files is the original that comes with P3Dv4.5. I think that maybe the original was disabled and renamed and want to make sure I'll not mess with anything.
Thanks in advance.
Cheers, Ed

If you have GSX installed, you should leave the file as it is. The vehicles_airport.gsx file is a BACKUP made by the GSX installer of the file as it was before you installed GSX. The vehicles_airport.bgl is the file patched by GSX to remove the default tow truck
