What is a .mcworld file?
It is the packaged world format used by Minecraft Bedrock Edition for importing and sharing worlds.
Can Java Edition open a .mcworld file?
No. Java Edition uses a world folder, commonly delivered as a ZIP. Choose Java output in MapMC instead.
How do I open a .mcworld file?
Download it on a supported device, choose Open with Minecraft, wait for import, and find it in the Worlds list.
Can I import a .mcworld file on a console?
Consoles usually cannot import browser downloads directly. Import on Windows or mobile first, upload to a Realm, then download the Realm world on the console.
Why did my .mcworld import fail?
Check free storage, keep the .mcworld extension, retry from the Files app, and remove any incomplete duplicate world before importing again.
Does MapMC make both Bedrock and Java worlds?
Yes. Select Bedrock for a .mcworld file or Java for a world ZIP.
