I've managed to download Minecraft onto my SandDisk USB thumbdrive.
But how do I copy all my worlds to it?


Worlds are saved in the computer hard drive.

If you open explorer and go to %appdata%, you will see .minecraft.


The subfolder saves contains the folders with the worlds you want.

subfolder saves

Tip: %appdata% is the same as C:\Users\George\AppData\Roaming, where you replace "George" with your name.

    On Linux the path is ~/.minecraft and on Mac it's ~/Library/Application Support/minecraft. The approach is the same.
