What is an MHTML file?
MHTML stands for MIME Encapsulation of Aggregate HTML Documents, a standard defined by RFC 2557 for archiving web content. Functionally identical to the .mht extension, MHTML files utilize the Multipurpose Internet Mail Extensions (MIME) protocol to bundle a webpage's structure (HTML) and dependencies (CSS, images) into a single archive, facilitating offline viewing and email transfer of complex web layouts.
How to open an MHTML file
Primary support exists within Microsoft-based browsers like Edge and Internet Explorer. Users on macOS or Linux may use browsers such as Vivaldi or Opera, which maintain strong compatibility. Alternatively, changing the extension to .eml allows some email clients to display the content as a message body.

What is a DOC file?
The DOC extension refers to the proprietary binary file format used by Microsoft Word versions 97 through 2003. It is structured around the Object Linking and Embedding (OLE) Compound File Binary (CFB) format, acting as a file system within a file that manages streams and storages for text, formatting, scripts, and metadata. Unlike modern XML-based alternatives, DOC files store data in binary records, which can make parsing complex and prone to corruption if the binary headers are damaged.
How to open a DOC file
Microsoft Word remains the primary software for full-feature support of the DOC binary format. However, owing to its ubiquity, most third-party word processors including LibreOffice Writer, Apache OpenOffice, and Corel WordPerfect provide reverse-engineered support for opening and editing these files. Google Docs also offers import capabilities, though complex formatting utilizing legacy OLE objects may experience rendering shifts during conversion.
