Terria world got deleted

If the console can read the memory stick try moving them to a different storage device and see if it will read them then.

If the console can't read the stick or the game won't load the worlds after moving then I'm afraid there's nothing that can be done about it. Sorry about the bad news.

i could get a hold of my old laptop but i had to put another account on it deleting mine in the process

:c in this case the worlds are gone buddy, sorry

You can try double checking if Minecraft worlds are still there via File Explorer:

Open the run window: Press Windows Key + R

Write %appdata%

Once you press enter you should be able to see this path:

username/appdata/roaming

Go back to appdata clicking on it

Now go to this path:

\Local\Packages\Microsoft.MinecraftUWP_8wekyb3d8bbwe\LocalState\games\com.mojang\minecraftWorlds

You should be able to see something like in the picture (folder name dont need to be the same)

Compress the folders and copy that file to a USB drive, finally uncompress the file, and finally paste the folders in your new computer following the same procedure explained above.

If you're not able to find those folders due to some account deletion from that PC.

Sadly your worlds are lost :c

Do you have access to your old laptop?
Worlds needs to be transferred manually

So, if you're able to access to your other PC, you can export the world from there and then import them in your account

If you don't have access to the old laptop, sadly your worlds are gone :c

Let me know, I'll be waiting for your reply
