.DOCMHTML File Extension

Archived MIME HTML document saved by earlier versions of Microsoft Word, a word processing application; contains HTML source code that represents the document in a format similar to the original .DOC or .DOCX file; used for viewing published versions of documents in a Web browser.

DOCMHTML files are no longer supported by Word. Instead, if you want to publish a document as HTML, you should use the .MHTML or .MHT extensions from the File → Save As dialog box.
