After working several hours, I created custom data for the natural parks in France. I just changed my computer, I use a Mac and in my old one, using Parallels, the folder for Skydemon was in the Mac side. Now I use a new Macbook Air but I use Bootcamp, so my windows partition is purely Windows. I downloaded Skydemon and I copied the folder, but probably in a wrong place, because the zones I defined do not appear. How should I proceed? I don't want to do all the work again ... Help please ...

I found the solution, in the Documents folder of Windows there is another SD folder, I copied there the Custom Data and everything is in order.
