Sorry if I was unclear, what I was referring to is the screen where you choose your Aircraft for your flight, as it’s where you keep your Aircraft I referred to it as a Hangar.
My question is if MSFS can quickly scan the community folder, for new/updated Aircraft or scenery when you click the window to enter that list of Aircraft, however as rhumbaflappy said, a button would be even better as you would only scan if you have added, or updated, item(s) to your community folder.
