Register file extensions on third party servers

In order 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 ZIP archives. MIME types are automatically registered with Windows Server 2003 Service Pack 2 (SP2).

For servers that are not Windows-based, you will need to register the MIME types manually. Please refer to the product documentation for your server 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.
