coip said:So would this method allow me to transfer back and forth my Windows 10 PC and Windows 10 Mobile worlds? Or are they incompatible? What I mean is that I'd like to earn the achievements naturally, in my own survival world, but I don't want to have to do it twice on my Surface and then again on my Lumia. As a side effect, I'd love to be able to work on the world on my Surface, then work on it on my Lumia, then work on it back on my Surface, and so on, until the world is complete. Can I do that manually or is that only do-able via Realms?
Create a world on one. Press export and then import that file on the other device.
