MHT files are file formats used to store and transmit web page content. MHT is the abbreviation of "Single File Web Page", which packages a complete Web page and its related resources into a single file for easy viewing and sharing without an Internet connection. MHT files use the MIME (Multipurpose Internet Mail Extensions) type multipart/related, which makes it possible to save the HTML code, images, stylesheets, and scripts of a Web page in one file.

The structure of the MHT file adopts a multipart structure, where each part is encoded using the standard MIME format. It mainly includes the following parts:

1. Header information: Contains the metadata of the file, such as title, author, date and MIME type, etc.

2. HTML code: Saves the HTML source code of the complete Web page, including text, images, links, scripts, etc.

3. Multimedia resources: including all images, style sheets, scripts and other media files used in the page, usually embedded in the MHT file in Base64 encoding.

4. Other related files: MHT files can store other related files, such as sounds, videos or Flash animations, in the form of links.

There are many advantages to using MHT files. First of all, it is a complete file containing all page elements, so the content of the web page can be viewed completely even without an Internet connection. Secondly, MHT files save storage space. Compared with offline saving of Web pages, only one file is needed to store all content instead of multiple files. In addition, MHT files can be easily shared with other users, who only need to open the file to view, edit, or print Web pages without installing additional software or browser plug-ins.

Although MHT files provide many conveniences, they also have some limitations. First, since it is based on MIME types, it can only be opened in applications that support MIME types. Secondly, the portability of MHT files is relatively low because different browsers may parse them differently, resulting in inconsistent display results. In addition, MHT files are more suitable for saving and transferring single pages, and may not work well for websites containing a large number of links and complex interactions.

In summary, MHT files are a convenient format for storing and transmitting web page content. It allows users to view and share complete web page information offline, reducing storage space usage and the number of files. However, due to its reliance on MIME type and browser differences, there are limitations and compatibility issues to be aware of when using MHT files.
