UPDATE: Added the ablity to keep saves on the portable device. Thanks to Kenny for the fix. Redownload the launchers if you want this ablity.
Hello again. Today I’m going to teach you to make your minecraft install portable. Basically this allows you to run Minecraft from a portable hard drive, USB stick, or even on a network share. Please note that your saves will still be stored in the Appdata directory of the current user (I know no workaround for this except to keep coping the saves).
You will need:
A Copy of Minecraft (perferably the latest);
An reasonably up-to-date Java install (it MUST be Java Runtime 6);
A Windows/Linux/Mac PC;
Some Spare Time.
You need to run Minecraft at least once.
1. You need a run box, so press Windows Key+R. If your running Windows 7 or Vista, just open the start menu.
2.type in “%appdata%” without quotes.
3.for Windows XP, copy the .minecraft folder to your final destination. for Windows 7 and Vista, you’ll find the .minecraft folder inside the Roaming folder. Copy that to it’s final destination.
4.Once it’s finished copying, rename the .minecraft folder to just minecraft.
6.Place these in the same folder as your minecraft folder.
7.You’re done! Run the Launcher to start playing.
1. Now, the .minecraft folder is in your home directory, and it’s a hidden folder. You need to copy that to it’s final destination.
2.Once it’s finished copying, rename the .minecraft folder to minecraft.
3.open up a terminal in that folder, then run this command: java -Xms512m -Xmx1024m -cp “minecraftbin*” -Djava.library.path=”minecraftbinnatives” net.minecraft.client.Minecraft “minecraftportable”
Some Extra Tips.
You probably saw the net.minecraft.client.Minecraft “mincraftporatble” bit in the command. the “minecraftportable” bit is your multiplayer name when you connect to a server which is in offline mode. Change that as you see fit. Windows users will find a similar command in their launchers; just open that file up in notepad and make the needed changes.
Also, be aware that any saves you create will be stored in the usual directory, not on your portable device.
