I’ve downloaded a load of packs from Flightsim.to
The Airfield and ‘Landmarks’ packs are not too big, approx 10 to 30 Mb.
The scenery packs can be beyond 2 Gb.
I have a ‘holding’ folder for Flightsim.to packs and copy across packs into Community folder if they are advantageous on my flight.
( For flyers with 16 Gb of RAM or less )
I have 32 Gb RAM now, but keep up this practice.
