Multipurpose Internet Mail Extensions (MIME) types instruct the user's Web browser to open a specific program for a file extension. MIME types are sometimes customized file types created by the website programmer. The MP4 MIME type is a video type, and it is configured in Internet Information Services (IIS) console. This instructs the user's Web browser to use the default video application when running this file from the website pages.
