Does anyone know what this folder is for?
C:\Users\USERNAME\AppData\Local\Packages\Microsoft.FlightDashboard_8wekyb3d8bbwe
Not to be confused with:
C:\Users\USERNAME\AppData\Local\Packages\Microsoft.FlightSimulator_8wekyb3d8bbwe
All folders are empty except:
C:\Users\USERNAME\AppData\Local\Packages\Microsoft.FlightDashboard_8wekyb3d8bbwe\Settings
which has 2 files: roaming.lock & settings.dat
Hey! Good to see you again 
FlightDashboard is completely separate from Microsoft Flight Simulator. I was also confused. I believe its a term used for the Xbox Insider Application.
Found this link: Flight Dashboard - Microsoft Community
Yep, I remember you! 
Originally I thought that it was related to the Alpha/Beta but the file data/time is yesterday 28AUG.
So MS calls the XBOX app “Flight”. Interesting!
Thanks!
You’re welcome!! I was in the same boat as well, the naming does throw you off a little bit
Have a good one.
