Press M for the menu + settings To save you have to export the chunk load list so when it comes on screen right click and then export it into a txt file. (you must be in the editor to export and import) Then to load you just have to put all the chunk data in. Be mindful that bigger files will lag the game and if they are big enough could become corrupt or simply cease to function.
