Upgrading SSD m.2 MSFS Drive from 1TB to 2TB?

[MSFSRonS]

Don’t know what the “R-Drive Image” is.

A clone is an exact copy of the drive that is being cloned.
Your C: is not that.

the dir Microsoft.FlightSimulator_8wekyb3d8bbwe seems to be missing from C:\Users\User\AppData\Local\Microsoft\WindowsApps. MS Copy protection?

It means that FS2020 is not installed.
