Addon Managers For Flight Simulator X and Prepar3D
Addit! Pro For Flight Simulator X
In the Select Addon Files screen I see a list of hard drives. Mine shows a:, c:, d:, e:, f:, g: and h: but I actually have c:, d:, e:, f:, g:, h:, k: and zip drive l:. How do I show all my drive buttons?
Resize the window to make it wider, then all your drives will appear. You may also need to resize the left panel (the one that lists folders).
