I like to keep everything out of my PC on a single, portable SDD, and Minecraft is no exception.

The official Minecraft launcher now roughly allows you to set a "game directory", but still, most of the data is stored locally.

There are a lot of tutorials about "portable Minecraft", but most of them are outdated and involve external utilities that are just useless if not dangerous (malwares).

But today we're going to fix that with a quick 7 steps tutorial. Straight to the point.

As of now I only know about Windows. I tried something similar on Mac but it didn't work, so if you know about that, DM me, thanks.

Here's the result: download.
(the link points to the old version, which may not work with the latest launcher, so follow the tutorial if you're having problems)


Here's the tutorial:

1. choose a folder for the game and add two sub folders: bin and data

2. get the latest Minecraft.exe from the site and put it in the bin folder

3. in the data folder create a .minecraft. folder: the second dot is important

4. if you already have Minecraft stuff installed, move those from the following directory to the new .minecraft folder

C:\Users\yournamehere\AppData\Roaming\.minecraft
5. now open the the Notepad from Start (don't just make a new text file!) and paste the following code

start "" "%CD%\bin\Minecraft.exe" --workDir "%CD%\data" --lockDir %CD%\data\.minecraft
6. save it as "minecraft.bat" with "All files" selected (important), in your game main folder (important)

7. now run the game using the minecraft.bat file and you're good to go!


Other important stuff

USB sticks are not made equal, and you need decent performance to run a game from an external device. Some tips to follow:

- size matters here: get enough space, at least 8GB

- get a fast USB, 3.0 is a must, check out for reviews, and get a stick with a high MB per second transfer rate

- format to exFAT (extended FAT, which is the new one) to handle big files and make the stick readable on both Windows and Mac or really anything. Just remember to make a backup of the data before cleaning the stick (you should know this by now :P)

Remember that you will still need Java installed.

THIS IS AWESOME! Thank you so much for the help!

As a quick note to anyone else trying this, as of 12/5/19 `Minecraft.exe` has been changed to `MinecraftLauncher.exe`.

Consequently, the code in your `minecraft.bat` file should read:
`start "" "%CD%\bin\MinecraftLauncher.exe" --workDir "%CD%\data" --lockDir %CD%\data\.minecraft`
rather than
`start "" "%CD%\bin\Minecraft.exe" --workDir "%CD%\data" --lockDir %CD%\data\.minecraft`.

If this changes again please post another reply here to keep everyone updated.

Thanks! :) <3

Just tried it Jan 2020 and it works. I needed a way to run a second account for server testing so I put it on a USB stick and it runs great.

The tutorial is about making the launcher portable - everything that happens next (game crashing etc) has nothing to do with this method, you should just follow regular troubleshooting practices: after the launcher is launched, everything is the same as with a normally installed Minecraft.

So, to wrap it up: if the game crashes, it's not because of the portable launch.

You should provide a download of a blank one that is setup but has never been run.
