Review of my scenery_packs.ini file; screenshot folder

It looks like you've done quite a bit of work organizing your scenery_packs.ini file. Let's take a closer look at your question.

• First and foremost, regarding the two ortho files (SCENERY_PACK Custom Scenery/z_ortho_Arizona_Grand_Canyon_HD and SCENERY_PACK Custom Scenery/yOrtho4XP_Overlays_v3), these should typically be included in the .ini file if you intend to use them in your simulation. They are used for representing particular real-world terrain (orthophoto) in high detail, so retaining them could be beneficial.
• The placement of the screenshot folder in your /Custom Scenery directory is not necessary. Screenshots do not need to be listed in the .ini file nor should they be stored in the /Custom Scenery folder. You may want to move this folder to another location for better organization. You can safely remove SCENERY_PACK Custom Scenery/Screenshots/ from the .ini file.

Your scenery_packs.ini file generally appears to be well-structured. Remember, the order matters, especially when there's overlapping scenery, so always place higher-priority scenery towards the top. X-Plane reads the .ini file from top to bottom, and the last entry of a specific location takes precedence.

In the context of X-Plane 12 and Microsoft Flight Simulator (2020), the principles of scenery ordering in the .ini file do not apply in the same way, so this information is specific to your current setup in X-Plane 11.

Final Thoughts:
Remember, X-Plane prioritizes scenery based on the order in the .ini file, with items higher in the list being prioritized over those below. If you experience any visual inconsistencies or conflicts within the terrain, you might need to manually adjust the ordering to suit your preferences. Feel free to reach out with further questions or any specific issues you may encounter.

Happy flying!
