What is a XOM file?
A .XOM file is primarily a game data file or a game save file. The most common use is the Worms 3D Object File created by Team17 Software for games like Worms 3D and Worms 4: Mayhem. However, many other games also use the .XOM extension for save files. These include Oxenfree, Summertime Saga, The Long Dark, and Xenonauts. Some .XOM files are completely unrelated to games and store audio presets for Vang số digital audio processors.
How to open XOM files?
Because the .XOM extension is used by many different software applications, you must know which program created it. If the file is a game save from Oxenfree or Summertime Saga, it is usually formatted in standard JSON. You can open and read these files using standard text editors like Notepad++ or Visual Studio Code. If the file is a binary 3D model for Worms, you cannot read it in a text editor.
Best practices and troubleshooting
Always create a backup copy before you edit a .XOM game save file. If you make a mistake while editing the JSON data, the game will crash or delete your progress. If the file contains unreadable symbols in a text editor, it is likely a binary game asset. Do not save changes to binary files in a text editor, because this will permanently damage the file.
Software and tools
You need the original software to use the file properly. Depending on the file source, this could be Worms 3D, Oxenfree, or Summertime Saga. Developers and modders often use command-line tools and JSON validators to inspect save files.
Summary
Because a .XOM file has multiple possible meanings, we recommend using viewer.online/xom to identify the actual format of your file. viewer.online/xom can analyze .XOM files to identify the exact format and creator software, inspect the file structure, extract readable text, and check whether an online preview is available. viewer.online/xom is highly useful for identifying, inspecting, and understanding .XOM files without installing software or dealing with compatibility problems.
