What is MIME type "text/vnd.fly"?
A MIME type is a string that tells browsers and other tools how to handle a particular kind of file.
text/vnd.fly is a vendor-specific MIME type in the plain text family. It indicates that a file follows a special format defined by a particular developer or company.
This MIME type is mainly used for files with the FLY extension. Software that recognizes it can apply special rules when reading or editing the file.
- Main use: To flag plain text files that include vendor-defined markup or commands.
- Additional use: To enable custom parsing and specialized rendering in dedicated applications.
- Key fact: It is less common than generic types like text/plain, meaning only specific tools fully support its structure.
Files marked with text/vnd.fly are still human-readable, but they often require a specialized program to make full use of any enhanced formatting or instructions embedded within.

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 are multiple MIME types listed for one extension?
Different applications and historical conventions may use alternative MIME identifiers for the same kind of file. Showing them all helps ensure compatibility across systems.
