I/m not sure about the 30 GiB... I see 109 GiB.

In your previous post, you wrote: I started at 1300 local time to install around 190 GiB.  It's now - 2030 local and I'm just approaching 30 GiB.
So it had taken about 7.5 hours to download/install 30GB. If I had to reinstall MSFS 2020, I think I could have downloaded/installed it twice (190GB x 2) in 7.5 hours. That's only a guess, because I didn't uninstall/reinstall it to test the length of time it would take.

So far, I have only had to reinstall MSFs twice, and it has installed in about 1.5 to 2 hours. The original install, at release, took about 4 to 5 hours to install, and had to restart the install twice. Installing the MSFS 2020 Alpha, and Beta, was faster than the original install of the Premium Deluxe version at release too. I have always put the long install time, at release, to traffic congestion due to lots of people downloading it at that time.
