A MIME type is a string that tells browsers and other tools how to handle a particular kind of file.
About .fsb Files
FSB files are a type of binary file used to store audio sample banks for applications such as games.
They are associated with the MIME type application/octet-stream which means the file holds raw binary data. This format was designed for the FMOD sound system, a popular audio middleware in game development.
- Main Use: Holding collections of audio samples for quick and efficient playback.
- Functionality: It bundles multiple sounds in one file, often with metadata that helps the FMOD engine retrieve and process audio data.
- Software: Programs such as FMOD Studio and various game engines (like Unity or Unreal when FMOD integration is enabled) can open and work with 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 .fsb file?
An .fsb file is an FMOD Sample Bank file used primarily in video games to store collections of audio sound effects and music. It is a container format created by the FMOD sound system to compress and organize audio assets for efficient playback within game engines like Unity or Unreal Engine.
How do I open or play an .fsb file?
Standard media players like Windows Media Player cannot open .fsb files directly. To play or view the contents, you typically need specialized tools such as FMOD Studio (for developers) or audio players with specific plugins, such as foobar2000 installed with the vgmstream component.
How can I convert .fsb files to MP3 or WAV?
To extract audio from an .fsb file, you can use utilities like FSB Extractor (Aezay), Music Player Ex, or vgmstream. These tools allow you to unpack the internal audio streams and save them as standard .wav or .mp3 files that can be played anywhere.
Why does my PC identify the .fsb file as application/octet-stream?
Because the .fsb format is a proprietary binary format without a universally standard MIME type, operating systems often label it with the generic application/octet-stream MIME type. This indicates to the system that the file contains arbitrary binary data that requires a specific application to interpret.
Can I edit an .fsb file?
Directly editing a compiled .fsb file is difficult and not recommended. These files are the output result of a build process in FMOD Studio; if you need to modify the sounds, you should edit the original source project files in FMOD and then rebuild the bank.
Is it safe to delete .fsb files found in game folders?
No, you should not delete .fsb files located inside a game's installation directory. These files contain essential audio data (such as voiceovers, music, and sound effects), and removing them will likely cause the game to have no sound or crash immediately upon launching.
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.
