Yes, I have been breaking computers with my pesky meddling for about 39 years 
I can’t imagine being told as a first time simmer - here is an Airbus a320, no manual, no tutorials, and OFF you go.
The console user should not care where his files are located obviously. Unfortunately they seem to have forgotten that this is a PC release not a port from console, and PC simmers need to twiddle with config files, and those with any sense at all absolutely have to have a manual - if only to point noobs in the right direction, and for that overwhelming feeling of satisfaction gained by correcting someone who is having a rant about some feature or other.
My advice: make a shortcut to the install folder and place on your desktop next to the MSFS icon. I think it is going to become more & more necessary to tweak stuff in there.
