Thanks guys for explaining these.
I think I have some better understanding of them now. I was wondering if the .agn files were autogen files and now I know. These files were located in my Texture folder of the KDFW or the Dallas Fort Worth airport scenery by fsdreamteam.
I have a question regarding making changes to textures of airport sceneries that are out of date. This airport scenery is the Dallas Fort Worth International airport scenery by fsdreamteam.
I was doing a real world flight from KATL to KDFW and when I arrived, I ran the GSX program to select my gate number, C33, so that ground crew would be ready when I arrive at the gate. But there was no gate C33 in the list of selections in GSX. I knew then that this airport had to be outdated. I check the airport file in ADE and sure enough, there is no C33. I was planning to make these changes and come to realize that the gate locations are also written on the pavement, or the tarmac, and these are texture files which also have to be edited. I parked at gate C32, which should be gate C39. Going back to the year when FSDT released this product, there was never a C32 at the location of C39 and I don't understand why this was implemented. C32 is not the only one that is wrong. They're all wrong, except C4. I can edit the gate number in ADE to C39 but the problem is that C32 will still be written on the pavement until I make those changes in the Texture folder. Of course, I would have to find the file.
But I'm not sure how to edit and make those changes in the textures. So, could someone explain how to edit this? I won't make any changes in the ADE until I can make the changes in the textures.
