What is an MHT file?
Most Web pages viewed in a Web browser only contain HTML and reference images and other media files that are stored in other directories on the server. Because all the files are encoded into a single file in a MHTML document, MHT files are commonly used to archive Web pages.
NOTE: Microsoft Word can save and open MHTML Web archives.
