Does this mean I can't deactivate the scenery to save VAS?
As explained so many times on the forum, it's totally useless deactivating FSDT or Flightbeam sceneries just to save VAS, it's a complete waste of time and effort, because the Addon Manager already does custom memory management for such sceneries, by removing all objects created at the airport, the moment you exit from its area, about 15.0 NM out.
I also have not installed Flightbeam KSFO and KPHX but it's put it in my Scenery library.. Obviously there are no Scenery or Texture folders but as I haven't installed those sceneries yet.
The installation has moved all the sceneries it found to be installed. So, if you see those sceneries there, it means they were already installed. Maybe you removed the files, but left their folders empty ?
I do not want my sceneries installed on my C: drive and understand that you don't have to do that. I have installed KLAX onto my E: drive and my Prepar 3D V3 and V4 installations are on my D: and G: Drive respectively.
You are really making it more complex than it is. It's just so simple: you can now install whenever you want, it doesn't matter where the sim is installed.
