Use the Add MIME Type and Edit MIME Type dialog boxes to create and edit Multipurpose Internet Mail Extensions (MIME) types. MIME types help clients handle new file name extensions appropriately. If IIS does not recognize the file name extension requested by the client, IIS sends the content as the default MIME type, which is Application. This MIME type signifies that the file contains application data, and it usually means that clients cannot process the file.
