Which MIME types are related to file extension ".fst"?
The .fst file extension is associated with 3 MIME types:
image/vnd.fst, application/octet-stream, text/x-fstar.
A MIME type is a string that tells browsers and other tools how to handle a particular kind of file.
About .fst Files
FST files are versatile files used in different applications. They can store image data, serve as game archives, or hold text-based content.
When the MIME type is image/vnd.fst, FST files hold image data in a vendor-specific format. They may require special image viewers or editing software that supports this unique format.
When the MIME type is application/octet-stream, FST files are used as game data archives by FASA Interactive. These archives often contain game assets such as textures, sounds, and configuration data that are processed by game engines or extraction tools.
When the MIME type is text/x-fstar, FST files are simple text-based files. They might store scripts, settings, or code in a format known as the FStar file format. This type can be opened with common text editors like Notepad++ or Sublime Text.
- Image Format: Uses image/vnd.fst for specialized image data.
- Game Data Archive: Uses application/octet-stream for FASA Interactive game assets.
- Text File Format: Uses text/x-fstar for plain text content such as scripts or configurations.
Based on information from FilExt.com, the main purpose of FST files depends on their context. Using the correct tool for each MIME type is key to opening or editing these files.
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 FST file?
An .fst file typically falls into one of three categories: a specialized image file, a game data archive used by FASA Interactive, or a source code file for the F* (FStar) programming language. To determine the correct software to use, you must know the file's origin.
How do I open an FST file containing code?
If the file is an F* source code file (associated with the MIME type text/x-fstar), it is a plain text file. You can open and edit it using any standard text editor or IDE, such as Notepad++, Visual Studio Code, or Sublime Text.
Can I open FST game files manually?
FST files used as game archives (often serving as application/octet-stream) contain assets like sounds and textures for games like Shadowrun or MechWarrior. These are usually binary files meant to be read by the game engine, though specific community-created extraction tools may allow you to view the contents.
How do I convert an FST image to JPG or PNG?
Conversion is only possible if you have the proprietary software that created the image/vnd.fst file. You would need to open the file in that specific viewer or editor and use the Export or Save As feature to convert it to standard formats like JPG or PNG.
What are the common MIME types for FST files?
The MIME type depends on the file's function: image/vnd.fst is used for vendor-specific images, application/octet-stream for game archives, and text/x-fstar for F* code. For a comprehensive list, you can check mime-type.com.
Why does my text editor show garbled text when opening an FST file?
If you see unreadable symbols or "gibberish," you are likely trying to open a binary game archive or image file in a text editor. This indicates the file is not a text-based F* script but rather a compiled format that requires specific game software or an image viewer.
Are FST files dangerous?
FST files are generally data files (images, text, or archives) and are not inherently executable. However, if an FST file contains a script or macro code, it should be treated with caution. Always scan files from unknown sources before opening them.
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.
