Complete uninstall and Reinstall of STEAM version MSFS 2020

Prior to launching the Steam ver 2020 , a file integrity check always has to verify and reinstall some files. I am assuming therefore that I have some corrupted files. I am also experiencing various Controller anomalies.
I therefore want to uninstall as clean as possible before reinstalling.
The main folder where MSFS2020 is installed is I believe…

C:\Users(name)\ AppData\Roaming\MicrosoftFlightSimulator … (some 481 GB)…which I believe can be left after the Steam uninstall.

Is it ok to remove this folder, and will it be reinstalled with the Steam installation process ?
Thanks…

Save your Community folder first.
Everything else will be re-installed.

You can un-install FS2020 via:

  1. Settings, Apps, Installed apps, MS Flight Simulator
  2. Xbox app

My knowledge is MS Store.
I don’t know about Steam.
