When you're done press the "Test" button and confirm that the version of Java it reports matches the version of Java in the box (in the screenshot above and in our test it read 1.8.0_25. Minecraft Portable/bin/runtime/jre-圆4/1.8.0_25/bin/javaw.exe Simply remove the drive letter and colon so that the entry in the box and MultiMC will look for the files relative to the drive it is located on: Where K: could be F, H, or whatever letter Windows has assigned to your flash drive. Assuming you've used the exact directory structure we've specified and created your batch file correctly the launcher should run, automatically download the components you need, and prompt you to log in with your Minecraft account.Īfter you've browsed to the Java executable the path in the "Java path:" box will look like: If the Minecraft launcher doesn't automatically launch, you may wish to add an additional line "PAUSE" to the batch file so keep the command window open so you can review any errors. Save the document and rename it "portableminecraft.bat". ![]() Navigate to the /Minecraft Portable/ folder and create a new text document. ![]() To that end we need to create a launcher batch file that sets a temporary variable for the APPDATA value. 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. The magic glue that holds together our little portability stunt here is a batch file. Note: Windows is very particular about creating folders and files starting with a "." in order to create your ".minecraft" folder without Windows yelling at you, append the end of the folder name with another "." like ".minecraft." and it will automatically remove the trailing mark and allow you to create the folder ".minecraft" without complaint. If you wish to start fresh, simply create the directory ".minecraft" inside the "data" folder. If you wish to use your existing Minecraft data copy the ".minecraft" folder (you can find the folder in your Windows application data folder, easily accessed by pressing WinKey+R to open the run dialogue box and then entering, sans quotation marks, "%appdata%" in the run box). ![]() Next you can copy your existing Minecraft data folder from your computer or create a new directory for fresh installation. Place the file, Minecraft.exe, in the folder /Minecraft Portable/bin/. Related: How to Back Up Your Minecraft Worlds, Mods, and Moreĭownload the file but do not run it. Our main Minecraft directory, packed with maps, mods, and useful Minecraft-related apps weighs in at around 14GB. To give you a sense of perspective on how much space you need a vanilla Minecraft install with only a few small worlds will take up approximately 300-500MB but once you start building out/exploring large worlds, adding in mods, downloading elaborate maps, and so forth you can easily max out an 8GB drive. Given how inexpensive they are, a good USB 3.0 flash drive with a decent amount of storage (8GB minimum) is in order. You can follow this tutorial with any quality removable media (or even follow it just to make a portable Minecraft folder on your main hard drive), but we opted to turn one of the flash drives we had laying around into a dedicated Minecraft portable drive with a Minecraft themed icon, naturally.Īs far as drive selection goes, this is not the time to recycle that 512MB USB 1.1 drive you have sitting in the bottom of a desk drawer. First we'll look at how to take a vanilla copy of Minecraft and make it portable and then we'll look at the more advanced MultiMC launcher that offers a more robust and flexible Minecraft management experience (and also lends itself very well to serving as a portable launcher). To achieve this end of easily portability/back up we'll walk you through two techniques. ![]() We run our installation of Minecraft as a portable installation for the latter reason yes, it's great that we can take it anywhere but the best part is we can back up everything by simply copying one directory. Today we're looking at two methods for turning your Minecraft experience into a portable one that allows you to not only park Minecraft and all your Minecraft data on a removable drive but, even if you're not bent on taking it on the road with a flash drive, to easily back up and restore your entire Minecraft experience in one swoop as all the files are contained in one directory.
