What is a PPSM file?

The PPSM (PowerPoint Macro-Enabled Slide Show) file format is a presentation file type developed by Microsoft, based on the Office Open XML (OOXML) standard defined in ISO/IEC 29500. Unlike standard PPTM files, PPSM files are configured to open directly in slide show mode rather than edit mode. The structure utilizes a ZIP-compressed XML framework containing a vbaProject.bin binary part to store Visual Basic for Applications (VBA) macros, along with separate folders for slides, media assets, and relationship (.rels) files.

How to open a PPSM file

PPSM files are natively supported by Microsoft PowerPoint (2007 and later) on Windows and macOS, which executes the contained macros upon opening if security settings permit. For users without the full Microsoft Office suite, files can be viewed using the free PowerPoint Viewer or LibreOffice Impress. On mobile devices, the Microsoft PowerPoint app provides compatibility, though macro execution is generally restricted on iOS and Android platforms.

What is an HTML file?

HTML (HyperText Markup Language) is the standard markup language for documents designed to be displayed in a web browser, defined by the World Wide Web Consortium (W3C) and the WHATWG Living Standard. An HTML file consists of plain text tags that structure content into a Document Object Model (DOM), enabling the embedding of scripts (JavaScript), cascading style sheets (CSS), and multimedia. The format has evolved from SGML-based roots to the current HTML5 specification, which includes semantic elements and APIs for complex web applications.

How to open an HTML file

Operating systems universally support HTML rendering via pre-installed web browsers like Microsoft Edge (Windows), Safari (macOS), or Firefox (Linux). For source code modification, developers utilize specialized editors such as Visual Studio Code, IntelliJ IDEA, or Notepad++. No proprietary software is required, as the format is an open, non-proprietary standard text file.
