About formats

PPSM (PowerPoint Slideshow with Macros) is a macro-enabled slideshow format in Microsoft PowerPoint, introduced with Office 2007 as part of the Office Open XML family. PPSM combines the auto-play slideshow behavior of PPSX with the VBA macro capabilities of PPTM — opening a PPSM file launches it directly into full-screen presentation mode while allowing embedded macro code to execute during the slideshow. The format is structurally a ZIP archive containing the same XML slide parts as other OOXML presentation formats, plus a vbaProject.bin stream housing the VBA project. This combination is particularly valuable for interactive presentations: macro-driven slideshows can respond to user input, navigate non-linearly between sections, query external databases, update content in real time, and log audience responses during training or assessment sessions. One advantage is interactive presentation capability — PPSM enables quiz-style presentations where clicking answer buttons triggers immediate scoring feedback, branching paths, or data recording, all invisible to the audience. The macro-enabled slideshow format also supports self-contained automation: a PPSM file can run initialization routines on launch, configure the display environment, and clean up resources on exit without any manual intervention. As with all macro-enabled Office Open XML formats, the distinct .ppsm extension helps administrators enforce security policies that differentiate between trusted macro content and standard presentations. PPSM is supported exclusively in Microsoft PowerPoint desktop editions.

EPUB (Electronic Publication) is an open ebook standard originally developed by the International Digital Publishing Forum (IDPF) and now maintained by the W3C following the organizations' merger in 2017. The first version carrying the EPUB name was approved in October 2007 as a successor to the Open eBook Publication Structure (OEBPS). An EPUB file is essentially a ZIP archive containing XHTML or HTML5 content documents, CSS stylesheets, images, fonts, and metadata organized according to the Open Packaging Format and Open Container Format specifications. The current major version, EPUB 3, supports reflowable and fixed-layout content, embedded multimedia, JavaScript interactivity, MathML equations, and rich accessibility features including semantic markup and media overlays for synchronized text and audio. A defining advantage is universal device support — unlike proprietary formats, EPUB works natively on virtually every non-Kindle e-reader, tablet, and reading application, from Apple Books and Google Play Books to Kobo and dozens of third-party apps. The reflowable text model is another core strength, automatically adapting pagination, font size, and margins to match any screen dimension and user preference. EPUB's open specification and active W3C stewardship ensure long-term preservation and vendor independence, making it the de facto standard for digital publishing across libraries, academic institutions, and commercial retailers worldwide.
