EDIT - solution found!! Guess you should always Google before asking any questions...here -> http://www.simforums.com/forums/problem-with-aivlasoft-after-install-of-gex-africa_topic39203.html is the answer to my own question below and appearently nothing to worry about.I have Aivlasoft EFB installed and when updating the FSX scenery data I got an error for a file called giza_image.bgl located in F:\Program Files (x86)\Microsoft Games\Microsoft Flight Simulator X\Scenery\0702\scenery. When inspecting the file I noticed it's file size is 0 bytes...Does anyone know anything about this file, if it's a default FSX scenery file or a file installed by some addon? To me it seems it got corrupted in some way and hopefully I could simply replace it if I only knew where it come from from the start.Thanks in advance for any help!

Hi Richard,I see you've found the answer to the meaning of the file, but if you install the AivlaSoft EFB 1.3.1 SP3 from here, you should see that EFB will henceforth not report "zero byte BGLs" as an error.

Thanks alot! Didn't know SP3 for EFB had been released.
