About .gtr Files
GTR files are specialized files that carry either retro music data or game archives.
The MIME type audio/x-mod means the file is a chiptune module used by the Spectrum Global Tracker. These files store musical data that tells a tracker how to play small audio samples to create digital retro tunes. They are common in music production using tracker software and can be played with compatible MOD players like OpenMPT.
The MIME type application/octet-stream shows that the file is a binary archive. In this use case, a GTR file acts as an ISI gMotor MAS type 0 game data archive. This means it bundles game data such as graphics, sounds, or level layouts for a specific game engine. It requires the appropriate game software to extract or use the data.
- Chiptune Music: Used for creating and playing retro digital tunes with trackers.
- Game Archive: Used for packaging game data for specific game engines.
Based on information from FilExt.com, the purpose of a GTR file depends on its source. Choose the right software—whether a tracker or game engine—to open and use it correctly.
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.

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.
