Tutorials/Playing and saving Minecraft on a thumb drive

Before beginning this tutorial, note that the following guides are only for the 2.0 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.

Instructions
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.

Before making the game portable, it is important to move all existing game data to the desired directory. Navigate to the portable drive in the file explorer, and create the  directory. Navigate to the  folder and copy all of its contents (but not the folder itself) into.

Once the game data has been moved to the new directory, you now need to move the launcher there too. Simply move  to.

Now all files are in place, the last step is to create a shortcut to the launcher. This shortcut must also be in. Once the shortcut has been created, right-click it and select Properties. In the Target field, append  to the end of the string that is currently there. Once done, the full Target field should read:.

The shortcut does not fully work, as it would cause errors if the letter assigned to the drive changed on another computer. Simply make a batch file called "start.bat" (Without quotes) and save the file in the  directory. Open the batch file with Notepad or another text editor and simply type , then save the file.

Everything is now finished. When you want to play, just use the shortcut batch file to launch the game. Do not start the launcher directly (without using the modified shortcut 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.
