Well this is wierd - I was wondering what the OP could have been talking about so I had a little dig around myself with a search and found two more(!) Community folders. Note that I’m on Steam and have my FS2020 install on my G drive together with a symlinked Users folder also on my G: drive
Both Community and Official folders here are empty:
but this path has a recent Community folder and an older Official folder:
the Community contains:
but the ‘Official’ is ultimately empty:
though what I can see is simply a collection of empty folders and not an actual file in sight.
My first suspicion is that one or more 3rd party app has gotten confused and created them at some point but I’m going to wipe the lot and see if they return.
