If you're playing at Minecraft for Windows, open the game and press Import world at the world selector, select the .mcworld file and wait until it finishes importing in-game.
Once you click the .mcworld file, Minecraft will open automatically. If your device says: "It doesn't have any app compatible with that file type" or "It doesn't allow you to access the Android folder", you must connect your device via USB to a PC and import it manually.
The "Import world" feature is only available at Minecraft for Windows client, we've verified and Android and iPhone / iPad client hasn't this version.
Download the file and unzip it as a folder.
Press Windows + R at the same time on your keyboard, and write: %appdata%.
Then, search for a folder named "Minecraft Bedrock".
Once in the folder, go to the folder named "Users".
Then, you'll find 3 folders: two of them have a really long number and the remaining one names "Shared".
Click on the folders with the numbers and open "games" and then "com.mojang" until you find a folder named "minecraftWorlds".
(If you don't find the folder named "minecraftWorlds" in the first/second folder, try to search at the other one).
Open it and cut/copy and paste the unzipped world folder to "minecraftWorlds".
Ppen Minecraft, find your world and the map will be available to play!
