All,
I am back to FTX Central 3. It took a day, but it felt good, till I started P3D and noticed that FTX scenery is not in the scenery file. I am not sure it has to do with me making the wrong symbolic link. One might think that is easy to do, but not for me apparently.
The amount of diskspace needed for Central 3 is 360 Gb i.s.o. 409 with Central 4. So the difference I expected is not that big.
I'll continue struggling with the symbolic link.
Regards
Hans
