Introduction The Office Open XML file formats are a set of file formats that can be used to represent electronic office documents. There are formats for word processing documents, spreadsheets and presentations as well as specific formats for material such as mathematical formulae, graphics, bibliographies etc. MHTML, short for MIME Encapsulation of Aggregate HTML Documents, is a web page archive format used to combine in a single document the HTML code and its companion resources that are otherwise represented by external links (such as images, Flash animations, Java applets, and audio files).
Technical details Office Open XML documents are stored in Open Packaging Convention (OPC) packages, which are ZIP files containing XML and other data files, along with a specification of the relationships between them. Depending on the type of the document, the packages have different internal directory structures and names. In practical terms, MHTML allows multiple elements of a web page-including images and other media that would typically be saved in a folder as separate files alongside an HTML document-to be saved altogether as a single MHTML file.
