I really want to play mc somewhere else wherever I find a pc so with friends or something. Would it be enough if you put the .minecraft folder on the usb stick from% appdata% or are there any complicated things you have to do.
All data from the Java Edition are saved in the .minecraft folder (if not changed)
I assume that you already have Minecraft on the USB stick and start with a .bat file.
Now you just have to insert the complete code into the .bat file:
"% CD% \ Minecraft.exe" --workDir "% CD% \ data \ .minecraft"
