What is an MLS file?

MLS files mostly belong to MLS Compiler. An MLS file may belong to two different groups. One version is a Multilingual String File used in software localization. In this case the file holds text strings in multiple languages that can be compiled by an MLS Compiler as part of systems such as the Teknum Multi-Lingual System. This file allows an application to choose the proper language version at runtime.
The other type is used as a level script in games. Files described as a Max Payne level script manage level data like object placement, triggers, and other gameplay events. An alternate description, Hitman Level Script, indicates similar functionality in different titles. More details about this game use can be seen at Max Payne 2.
Both forms are stored as plain text. You can open them with any text editor. However, be cautious; editing without the right tool (such as a dedicated MLS compiler or a game modding tool) may cause errors.
Common points include:
  • Text-Based – Content is stored in a readable format.
  • Dual Purpose – It handles both localization strings and game level data.
  • Context-Dependent – The file’s structure adapts to its intended role.
  • How can I open an MLS file?

    You need a suitable software like MLS Compiler to open an MLS file. Without proper software you will receive a Windows message "How do you want to open this file?" or "Windows cannot open this file" or a similar Mac/iPhone/Android alert. If you cannot open your MLS file correctly, try to right-click or long-press the file. Then click "Open with" and choose an application. You can also display a MLS file directly in the browser:. Just drag the file onto this browser window and drop it.
