Getting a Minecraft Realms save file from a locked account

Is it not possible for a staff member to send me a copy if I prove I own the account?

Unfortunately nope.

Sorry, no one can access to your account or similar.

Hi and thanks for reaching Microsoft Xbox gamer's community. My name is Josef.
I'm an Independent Advisor and a Microsoft Xbox user like you.

Hope you're doing great today despite this Eden

Unfortunately only the owner / creator of the realm can download a copy and then transfer it to other people :c
As you're not able to access to the account that owns the realm is not possible to do something.
Sorry

Hello slyryx,

Welcome to the Xbox Community Forum. Thank you for sharing your concern with us today and we hope that all is well.

As per Minecraft Support: It can be difficult to transfer game files from one device to another. However, there are two methods that can help you transfer your worlds. You can transfer worlds between these devices using a Minecraft Realm or, if you play on an iOS device, through the iCloud method.

Transfer Your World Using a Realm

You must have an active Minecraft Realm to do this. If you have not yet used your Realms free trial, you can use that to transfer your worlds. For more information about Minecraft Realms and how to start a Realm, go to the Realms Plus page.

Note: You must use the same edition of Minecraft and the same Xbox Live account to transfer worlds.

1. From the first device, click the pen icon next to your Realm from the Realms list
   
2. Click Replace World and confirm.
   
3. Choose the world you want to transfer.
   
4. Wait for the upload and then click Let's go!
   
5. Open Minecraft from the second device and click the pen icon next to your Realm from the Realms
   
6. Click Download World.
   
7. Wait for the download and then click Let's go!
   

Your world should now be transferred from one device to another. If you want to transfer another world, repeat the same process.

Transfer Your World Using the iCloud Method (iOS Devices Only)

See the steps below for the Apple iPad:

1. Open the Files app on the old iPad.
   
2. Under Browse, tap On My iPad.
   
3. Tap Minecraft.
   
4. Tap the Games folder.
   
5. Tap the com.mojang folder.
   
6. Locate the file named minecraftWorlds. This has all your worlds in it.
   
7. Press and hold to open the menu.
   
8. Tap Save to Files.
   
9. Locate your iCloud drive and save the world file to the iCloud Drive folders where you want to store it.
   
10. Click Save.
    

The worlds are now saved to your iCloud.

Hello Stiffy Fungus,

Thank you for posting here on the Xbox forums. I don't play Minecraft myself, so I can only bring in information from the developers website.

You can find their realms page here :
Minecraft Realms

Along with their FAQ here :
Minecraft Realms FAQ

I searched through both links, and there was no mention of being able to download other peoples realms. As far as getting a copy from Windows, that would be impossible as well since nothing is transferrable between accounts. This includes game saves.

For more specific info regarding Minecraft, check out the
Minecraft support site and
official forums.

Hope this helps!
