The MIME type

MIME (Multipurepose Internet Mail Extensions multipurpose Internet Mail Extensions | Internet media type) is a kind of used to represent the document, file, byte stream properties and format standards; Defined and standardized in IETF RFC 6838M

MIME specifies symbolic messages used to represent a wide variety of data types. In addition, the MIME framework is used in the HTTP protocol, and the standard is extended to include Internet media types

MIME types are often used in browsers to determine how urls should be processed. Using the correct MIME type in HTTP response headers is important for processing files correctly. However, MIME types are not the only way to convey information about document types
