What is .mht Files?
.mht is a file extension of MIME HTML, or in short, MHTML or sometimes referred as MHT. This is a format for webpage archive and is used for combining resources. These resources are usually represented by external links. This webpage archive is formatted using MIME HTML, which saves HTML to:
Images,
Flash Animations,
Java applets, and
Audio files.

Using the MIME type “multipart/related”, Contents of the MHTML file is encoded and treated just like an HTML e-mail message.

Generally, the first part of the file is encoded with HTML, the next succeeding parts are just additional resources that contain their original URLs and encoded with base64.

The .mht suffix is a given default when it is created using Microsoft Word, Internet Explorer, and Opera. Most web pages viewed in a web browser only contain HTML and reference images and some media files that are stored in other directories in the server. In addition, since the files are encoded into a single file in a MHTML document, .mht files have been a common used file in archiving web pages.

The .mht files are created when you use the “Save” functions of some web browsers.
