What is the difference between .tnef and .mhtml?

Name: Transport Neutral Encapsulation Format; MIME HTML File
Extension: .tnef; .mhtml
Format: Binary
Category: Email; Developer
Developer: Microsoft; Microsoft
Description: File generated by Microsoft Exchange email programs such as Outlook; appears as an email attachment for email clients that don't recognize Microsoft's proprietary TNEF format; may cause the text "application/ms-tnef" to appear in the email if the email client does not recognize Microsoft Exchange formatting.; MHTML, short for MIME HTML, is a file format that archives web pages. The format combines HTML code, images, JavaScript, and other resources into a single file using MIME type multipart/related. This method of encapsulating a complete webpage (or set of webpages) in a single file makes MHTML files convenient for saving, sharing, and viewing web content offline. MHTML files typically have the extension .mhtml or .mht and can be opened by various web browsers.
MIME Type: application/vnd.ms-tnef; application/x-mimearchive
