finally i placed all of our community created sceneries into D:\Aerofly FS 2 Flight Simulator AddOns\scenery. There i created a folder for example Germany ( or the name of a town ) with subfolders images, places and elevation. I copied the of our community created sceneries images, places and elevation files and placed them into the subfolders.
My request is that our excellent scenery creators would create their folders also like i did.
It works. My diskspace on C where Windows 10 is located became smaller and smaller. Most of us should have partitions of their harddisk or two separated disks ( SSD and HDD or
two SSDs ).
Perhaps i can help saving diskspace.
