From what I have read, as of now you can't. I just started playing again with the Reach port (on Xbox) and I guess back in August they had a "one-time transfer" where they allowed players to fully transfer their file shares but it was only for like a week I think. Very lame. The new file share system sucks.Does anyone know if this can be done? I would absolutely love to import worlds that my friends and I made all those years ago.
