Our main Minecraft directory, packed with maps, mods, and useful Minecraft-related apps weighs in at around 14GB. With your flash drive selected, if you want to follow along in our purely cosmetic footsteps and add custom icon to your portable Minecraft flash drive the process is very straight forward. First, you need to locate an appropriate icon to use. Although you could fuss around with creating your own.
Once downloaded we copied it to our flash drive and renamed it minecraft. With the icon on the drive you just need a little bit of code to prompt Windows to use the. Create a text document in the root of the flash drive and paste the following code into it. Save the file as autorun.
There are two hurdles to successfully running vanilla Minecraft as a portable application. First, we need to tell Minecraft to look for its game data in a local directory and not in a system wide application data directory as it does with a default installation. Not only are tidy directory structures useful for knowing exactly where your stuff is they also make creating the shortcuts and batch files that make the portable Minecraft magic happen much easier.
The first stop is to either grab a fresh copy of the Minecraft. We recommend getting a fresh copy from the official website as this tutorial relies on you using the updated launcher that supports localized Java. Download the file but do not run it. Place the file, Minecraft. Next you can copy your existing Minecraft data folder from your computer or create a new directory for fresh installation. At this point you should have a directory structure that looks like the map above with the Minecraft executable and game data directories nested in the appropriate subdirectories.
The magic glue that holds together our little portability stunt here is a batch file. We need to both launch Minecraft and simultaneously create a temporary association wherein Minecraft can use the local data folder we created as an application data folder instead of defaulting back to the system wide application data folder.
Paste the following text into it. Go ahead and log into your Minecraft account as we need to access the launcher and profile data in the next step to confirm that it is using the local appdata and Java instances.
Run the portableminecraft. Look down at the bottom for the profile selection menu and the edit button, as seen in the screenshot below. Click the play button on the main launcher pane and wait for the required game files and assets to download to your portable Minecraft directory. Although we anticipated a performance hit for running the game off a flash drive, other than a few stutters when the map first loaded everything ran super smoothly.
The consistent 75 FPS matches the the same performance we get when playing Minecraft from our main hard drive. In short, MultiMC is, as the name suggests, a tool for managing multiple instances of Minecraft. By its very nature MultiMC is portable as it stores all the Minecraft data in a central location. The only weakness in the current MultiMC release 0.
There are two approaches you can take to fixing this problem. You could install a portable version of Java ala the jPortable installer found over at PortableApps. How you handle accessing the Mojang-packaged version that ships with Minecraft is a personal choice. The former technique is preferable as it allows you to update the Java bundle in place by simply running the vanilla Minecraft launcher. Regardless of whether you install a separate copy like jPortable , piggyback on the portable copy you installed in the previous section, or copy over the java directory from your main Minecraft installation on your computer, we need to show MultiMC where to find it.

Thank you for reading this Instructable and let me know in the comments if you have any questions about anything I did in this Instructable. So, assuming you have already purchased Minecraft, you are going to want to head over to the Minecraft Homepage. Once you are at the homepage, you will see a Log In button on the top right side of the page. Click this button and fill in your login info. After you have logged in, hit the Orange download button and you will see a large page full of text.
Click the Minecraft. Ok, so you have now downloaded the Minecraft. Now, you should move that file to your USB drive. To do that, find the file that you downloaded and then drag it onto your usb drive folder. You should see that now there is a Minecraft.
