For servers to recognize the new file formats, you will need to register the Multipurpose Internet Mail Extensions (MIME) types for each new file type. If the MIME types are not registered, servers will detect the new file formats as archives of compressed files. MIME types are automatically registered with Windows Server 2003 Service Pack 2 (SP2) or later versions.
By default, Internet Information Services (IIS) 7.0 includes these new MIME types. For servers that run Windows Server 2003 and Internet Information Services (IIS) 6.0, you can add the Open XML types in IIS Manager. For more information, see Configure MIME Types (IIS 6.0) (https://go.microsoft.com/fwlink/?LinkId=158193).
For servers that are not Windows-based, you have to register the MIME types manually. Refer to the product documentation for your server or refer to the links at the end of this article for more information about registering MIME types.
The following table shows the extensions you will need to register, their file type, and their MIME type.
