A MIME type is a string that tells browsers and other tools how to handle a particular kind of file.
About .luau Files
LUAU files are plain text files containing source code written in the Luau language. They use the MIME type text/x-lua which tells systems to treat them as script files.
They are mainly used in game development, especially on platforms like Roblox. Developers write code in these files to control game logic and behaviors.
Key details include:
- Main Use: Scripting in game environments.
- Format: Plain text with programming commands.
- Editors: Viewed and edited in apps such as Roblox Studio, Visual Studio Code, or Notepad++.
- MIME Association: The text/x-lua MIME type aids in syntax highlighting and proper file recognition.
Relationship between file extension and MIME type
A file extension is a suffix at the end of a filename that indicates what type of file it is. File extensions help both users and operating systems identify what application should be used to open the file.
File extensions are typically separated from the filename by a period (dot) and consist of 2-4 characters, though they can be longer. For example, in the filename "document.pdf", ".pdf" is the file extension.
File extensions are closely related to MIME types, as they both serve to identify the format of a file. However, while MIME types are used primarily by web browsers and servers, file extensions are used by operating systems and applications.

FAQs
What is a .luau file?
A .luau file contains source code written in the Luau programming language, which is a derivative of Lua tailored for high performance and robustness. These files are primarily used in Roblox game development to define game logic and mechanics. They are plain text files often associated with the MIME type text/x-lua.
How do I open and edit a .luau file?
Because they are plain text, you can view them in any basic text editor like Microsoft Notepad or Apple TextEdit. For coding, it is highly recommended to use Visual Studio Code (with the Roblox LSP extension) or Sublime Text to get proper syntax highlighting and type checking features.
What is the difference between .lua and .luau files?
Luau is a superset of Lua 5.1, meaning it includes features that standard Lua does not, such as gradual typing and performance optimizations. While a standard Lua interpreter can run basic code found in a .luau file, it will likely fail if the script uses specific Luau syntax or type annotations.
Can I run a .luau file directly on Windows or macOS?
No, you cannot double-click a .luau file to run it like an application. These scripts require a host environment, such as the Roblox game engine or a standalone Luau CLI interpreter, to execute the code contained within them.
How do I convert a .luau file to standard .lua?
You can rename the file extension from .luau to .lua, but this does not convert the code logic. If the script uses Luau-specific features (like type definitions), you must manually edit the code to remove those elements so it becomes valid standard Lua.
Why isn't my text editor highlighting the syntax correctly?
Your editor might not automatically recognize the .luau extension. You can fix this by installing a specific extension for Luau or by manually configuring your editor to treat the file as text/x-lua. See more about this MIME type at mime-type.com.
Are .luau files safe to open?
Yes, opening a .luau file in a text editor is safe because it is just text. However, you should be cautious about executing downloaded scripts inside Roblox Studio or other interpreters if you do not trust the source, as scripts can contain malicious game logic.
General FAQ
What is a MIME type?
A MIME (Multipurpose Internet Mail Extensions) type is a standard that indicates the nature and format of a document, file, or assortment of bytes. MIME types are defined and standardized in IETF's RFC 6838.
MIME types are important because they help browsers and servers understand how to process a file. When a browser receives a file from a server, it uses the MIME type to determine how to display or handle the content, whether it's an image to display, a PDF to open in a viewer, or a video to play.
MIME types consist of a type and a subtype, separated by a slash (e.g., text/html, image/jpeg, application/pdf). Some MIME types also include optional parameters.
How do I find the MIME type for a file?
You can check the file extension or use a file identification tool such as file --mime-type on the command line. Many programming languages also provide libraries to detect MIME types.
Why can one extension have multiple MIME types?
Different programs and historical usage may assign various MIME identifiers to the same file format. Listing them together helps maintain compatibility across tools.
