About .fsx Files
FSX files are F# script files that contain code written in the F# programming language.
They are plain text files marked with the MIME type text/x-fsharp.
- Primary Use: They are used for scripting, testing, and prototyping F# code.
- Execution: Run within the F# Interactive environment (fsi.exe) or through IDEs like Visual Studio and Visual Studio Code (with Ionide).
- Flexibility: Ideal for small code samples, automation, and embedding scripts into larger projects.
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 an FSX file?
An FSX file is a script written in the F# programming language, often used for lightweight scripting, data analysis, or prototyping. Unlike standard source files, these allow developers to execute code immediately using F# Interactive (fsi.exe) without compiling a full application.
How do I open and edit an FSX file?
Since FSX files are plain text, you can open them in simple editors like Notepad or TextEdit. However, for the best experience with syntax highlighting and IntelliSense, it is recommended to use Visual Studio, JetBrains Rider, or Visual Studio Code with the Ionide extension.
How do I run an FSX script from the command line?
If you have the .NET SDK installed, you can run a script by opening your terminal or command prompt and typing dotnet fsi filename.fsx. This invokes the F# Interactive tool to execute the code contained within the file.
What is the difference between .FS and .FSX extensions?
The .fs extension represents source code files intended to be compiled into a binary (like a .dll or .exe) as part of a larger project. The .fsx extension is strictly for scripts meant to be run interactively or individually without a project file (.fsproj).
Are FSX files dangerous?
As with any executable script (like .bat or .ps1), FSX files can perform operations on your file system and network. You should only run .fsx files from sources you trust, as malicious code could harm your system.
What is the correct MIME type for F# scripts?
The generally accepted MIME type for F# source and script files is text/x-fsharp. If you are configuring a web server to serve these files, you can check specific configuration details on mime-type.com.
Can I convert an FSX file to an EXE?
You cannot directly convert the script file itself to an executable. To create an application, you must create a new F# project, move the code from your .fsx file into a .fs source file, and compile the project using Visual Studio or the .NET CLI.
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.
