I don't know if anyone has thought of this idea before but here it goes. My idea is to have an option for saved games where you can choose which drive and folder the world is saved to instead of always the usual .minecraft/saves or whatever its called. This would give players who have more than one computer the ability to save their world to a flash drive or even a cloud service like Dropbox where their world could be accessed from either computer not to mention making backing up worlds much easier. If the computer fails for any reason, just disconnect the USB drive. Thoughts?
Go to the official minecraft.net webpage and download Minecraft. The first option that appears as a grass block.
*Now I saw your attachment. Same version...
I really don't know, try downloading it again.
**I've just realized that the translations are not exact. My launcher has a Profiles (perfiles) tab and the English version is Launch options (Opciones de lanzamiento). Possibly changed so it doesn't use much space.
This changes the game directory! With versions, mods ...
It is telling to put export of worlds in Minecraft
The directory saves not just mods, resource packs, etc., but it also stores worlds there too. You can just then duplicate the world file onto whereever you want after you make the directory in a place you can easily get to.
