I reinstall MSFS 2024 after every larger update. Is there any way I can deactivate the bespoke airports besides disabling them one by one in my library? I own very many 3rd party airports, so I have to spend a lot of time cleaning up my library every time. Any suggestions appreciated!!
Hi!
Here’s how I do it:
Go to this path: C:\Users\YourUsername\AppData\Local\Packages\Microsoft.Limitless_8wekyb3d8bbwe\LocalCache"Here you’ll see a folder with your username."
Inside, you’ll find the content.xml file (I recommend loading a new, empty one into the community folder and deleting this content.xml file. Open MSFS 2024; a new one will be generated with everything set to default). (In my case, I saved two: the default and the optimized one). For the optimized version, use the Addon Linker plugin and in the Tools section, then in the content.xml editor, look for Airport (Be careful with this, as you’ll see “airport base,” “airport library,” etc.). Once it’s to your liking, save it. Use this saved version for each clean installation so everything is set up the way you like it.
