The MJ3 file extension is a Minecraft world data file created by the Id Software application and is mainly used to store in-game data like gameplay environment setup, items, and player characters. MJ3 stands for "Minecraft Java Edition Version 3" and is the latest version of the popular multi-player game.
The MJ3 file extension functions as a configuration container that stores images, structures, materials, font size, items, worlds, and core settings related to the game layout. Additionally, the world itself is made up of blocks with a 16x16x256 grid system. It is also used to save and share worlds with other players.
Structure
An MJ3 file contains source code in XML (Extensible Markup Language) format that is structured so that the application reading it can properly interpret all the objects within the game. Specifically, the file contains information about different blocks or chunks arranged in grid coordinates on x-, y-, and z-axis. The game can read these coordinates to simulate the visual environment of the world within Id Software's Minecraft software.
Supported File Extensions
MJ3 files can also be opened with other applications such as MCEdit, WorldEdit, PocketMine-MP, and MagicaVoxel. Other similar file extensions are .LSM
Summary
The MJ3 file extension is used by Id Software’s popular multi-player game Minecraft to save and share worlds with other users. The MJ3 file contains source code in XML format which contains information about different blocks or chunks arranged in grid coordinates. It can also be opened with other applications such as MCEdit, WorldEdit PocketMine-MP, and MagicaVoxel. Similar file extensions include.LSM,.MRG, and.PRT.
After installing the required software, the operating system will usually automatically associate an unknown file type (in this case .MJ3) with the new application. If this does not happen, we can help the system a bit by selecting the software for it, which it should always use to open files with the .MJ3 extension.
When choosing the software we can select the system to use this software every time.
Remember!
Using it for the first time it is good to check whether the .MJ3 file opened in the application can be read by us and opens in a way that allows us to use it. If everything is in order, select this option the next time you open a file with the .MJ3 extension. However, if the file has not opened correctly, we have to look for a different software, with which we can open files with the .MJ3 extension. Select a different software from our list and install it on your computer. After the software is installed, repeat inspection openings of a .MJ3 file. Sometimes you have to repeat the operation several times.
Other instructions
If none of the programs listed by us to work with the .MJ3 file has not meet your expectations, you can try searching other websites. But remember to avoid downloading programs "that can open any file". These applications not only have very limited functionality, but may also expose you to expense tens of dollars when purchasing a license.
In the vast majority of cases you will find the program dedicated to support the .MJ3 file, or any other file format. In addition, there is a chance that it will be a free program, and its functionality (concerning the .MJ3 file) will be extended to the maximum.
It is also good to check
- if the .MJ3 file has no errors
- or if it has been copied (or downloaded by the browser) thoroughly
