in your case that you have indicated above, inside the ‘Packages’ folder - you should have two folders -
One is called ‘Community’ and the other is called ‘Official’
That ‘Community’ folder is the actual folder where you would place your freeware and payware addons. I know of no other ‘community’ folder that would work and really no other such folder should exist in the MSFS directory.
I am not going to talk about putting a shortcut to that folder on your desktop or anywhere else at this point as it would likely confuse the matter more…somehow.
