If you're playing this variant, knowing where your worlds are stored is important to easily back up your progress. Bedrock Edition worlds are stored in a folder on your device.

Sometimes Minecraft players require the ability to make a copy of or "back up" a given world for various reasons.

You can easily keep your copy of "Minecraft: Java Edition" up to date via the Minecraft Launcher app. This is the app you open and press "Play" in to start the game.
