About .flm Files
FLM files are specialized files with two main roles.
Stunt Island Film FLM files use the MIME type application/octet-stream. They store binary film data. This type is often used by the Stunt Island game to manage in-game cinematic scenes or cutscenes. Some specialized media tools or game editors may open them.
Flasm disassembled ActionScript FLM files also appear as plain text with the MIME type text/plain. They hold disassembled Flash ActionScript bytecode. This form is produced by tools like Flasm for code analysis or debugging and can be opened in any text editor.
- Stunt Island Film: Contains binary film assets for game animations.
- Flasm Disassembled Bytecode: Stores plain text code for Flash debugging.
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 FLM file?
An FLM file is typically associated with one of two distinct formats: a saved film file from the vintage game Stunt Island, or disassembled ActionScript bytecode created by Flasm. The Stunt Island format contains binary animation data, while the Flasm format is a plain text file used for modifying Flash SWF files.
How do I open an FLM file created by Flasm?
Since Flasm-generated FLM files contain plain text, you can open them with any standard text editor such as Notepad, Notepad++, or Visual Studio Code. These files display disassembled ActionScript bytecode, which developers edit to debug or modify the behavior of a Flash application before reassembling it.
Can I play Stunt Island FLM files in VLC or Windows Media Player?
No, standard media players like VLC cannot play Stunt Island FLM files because they are not standard video containers (like MP4 or AVI). They contain proprietary game engine data that only the original Stunt Island software can interpret and render as a cinematic scene.
How can I convert a Stunt Island FLM file to a modern video format?
There are no direct file converters for this proprietary format. To convert an FLM file to MP4 or AVI, you must run Stunt Island (usually via an emulator like DOSBox), play the film within the game, and use screen recording software like OBS Studio to capture the playback.
What is the correct MIME type for FLM files?
The MIME type depends on the file's content. Flasm files are text-based and are generally treated as text/plain. Stunt Island film files are binary data and usually default to the generic application/octet-stream type on web servers.
How do I use FLM files to edit Flash SWF files?
You first use the command-line tool Flasm to disassemble a .swf file into an .flm file. After editing the ActionScript code in the FLM file using a text editor, you use Flasm again to reassemble the FLM file back into a functioning SWF file.
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.
