Tutorials/Playing and saving Minecraft on a thumb drive

Before beginning this tutorial, note that the following guides are only for the 2.x launcher. If you want to make minecraft portable for an older launcher version, please view this page instead

This tutorial explains how to run Minecraft on a portable drive. This is useful if you want to retain your game data (launcher profiles, worlds, resource packs, etc.) when switching computers.

The primary focus of this guide is to create an installation of Minecraft on a portable drive. However, the exact same steps can be followed to create a portable installation of the game; that is, an installation that is not "integrated" with the computer, which is useful for managing multiple installations and generally keeping things organised.

Note: After this guide the game will be only 99% portable: the game data will be stored and used by game and its launcher where you want but launcher will create  directory anyway and will be placing there its log files (like update logs, logs with game messages and crashes, etc.)

Instructions (for Windows)
Note: The following Windows tutorial will guide you through installing the game to. However, this guide can be used to install the game to any directory. When following this guide, replace this directory with the directory you actually want to install the game to. Please also note that while this guide was written for Windows, it is still largely applicable to other operating systems with minor changes.

Navigate to the portable drive in the file explorer, and create the  directory. Next, create  folder for launcher with its data and   folder (or another name of your choosing) for game data.

If you have existing game data, you can move it to the desired directory. Navigate to the  folder and copy all of its contents (but not the folder itself) into.

Now you need to move the launcher. Download  (if you don't have it) and move it to.

Create an empty text file called  (or another name of your choosing) in the   directory.

Open the batch file with notepad or another text editor and paste the following text into it before saving the file:

Everything is now finished. When you want to play, just use the batch file to launch the game. Do not start the launcher directly (without using the batch file), or the game will just use the default directory in  as its working directory. It is recommended to set the launcher's executable to have the "hidden" attribute to avoid accidentally running it. You could also make a shortcut on the Desktop to run the bat file without having to find it.

Instructions (for Linux)
Note: The following tutorial assumes that the USB disk is located (and mounted) at, and that you would like to have portable minecraft at.

Start by creating directory for the game:

Next, create  folder (or another name of your choosing) for your minecraft game data:

Now, at this point, if you would like to copy all your existing game data, run the following command:

You now need to download the Minecraft Launcher. Do so by running the following command:

Next, extract the  folder by using your favourite extraction utility. This tutorial assumes the extracted folder is located in.

All the basic setup is completed. You will find the launcher at

To open the launcher correctly, run the following command:

You can paste this into a shell script and run it when you want to play Minecraft.
