MIME stands for Multipurpose Internet Mail Extensions. It's a method of categorizing files on the Internet based on their nature and format.
MIME types are a way to label the types of data so that programs can process the data correctly. For example, MIME types can help a browser determine what type of content is about to be processed so the browser can use the proper protocols, media player, codec, or plugins to display the data correctly.
For example, the MIME types file maps the extensions .html and .htm to the type text/html: type=text/html exts=htm,html.
When a web server delivers a web page to a client's web browser, it also sends the MIME type of the data it is sending. If there is an attached or embedded file in a specific format, IIS also tells the client application the MIME type of the embedded or attached file. IIS can only operate on files of registered MIME types. These types could be defined both on the global IIS level and on the website or virtual directory level.
