What is PPTX File Format

Open XML Presentation (PPTX) is a file format for storing presentations in XML format, developed by Microsoft. PPTX is a zipped, XML-based file format used for storing slide presentations. It is a successor to the PPT format and is used by Microsoft PowerPoint 2007 and later versions. The PPTX file format is based on the XML schema and uses a ZIP compression algorithm. PPTX files are stored in a folder structure, which contains a document.xml file, a slide master file, and a number of slide files. The document.xml file stores the content of the presentation, while the slide master file stores the layout and design of the slides. The slide files store the individual slides in the presentation.PPTX files can be opened in PowerPoint 2007 and later versions, as well as in some other presentation software.

What is MHTML File Format

MHTML, short for MIME HTML, is a web page archive format used to combine resources that are typically represented by external links (such as images, Flash animations, Java applets, and audio files) with HTML code into a single file. The resulting file can be saved and opened by web browsers.MHTML is supported by most major web browsers, including Microsoft Edge, Internet Explorer, Google Chrome, Mozilla Firefox, and Opera. Safari has limited support for MHTML. When a web page is saved as an MHTML file, the HTML code and the resources are typically encoded using the MIME type multipart/related. This type of encoding is necessary in order to maintain the correct sequence of the HTML code and the resources when they are combined into a single file. The MHTML format is often used for archiving web pages or for distributing web pages that need to be viewed offline.
