A

Word uses the Single File Web Page format to store text, pictures and objects from the original word document into a single file with the Web Archive (.mht) file extension.

The Single File Web Page format is also known as a Web Archive File format. It uses the MIME Content-Type "multipart/related" to bundle multiple files into a single archive file. The first file bundled in the archive file is normally the HTML document of the Web page. Subsequent files bundled in the archive file are additional supporting files to the Web page.

Image files and other binary files are encoded in Base64 format in a Web Archive file.

Here is an example of Web Archive (.mht) file generated by Word:

MIME-Version: 1.0
Content-Type: multipart/related; boundary="----=_NextPart_01CA4105.13A346F0"
