About formats

MOBI is an ebook format originally developed by Mobipocket SA, a French company founded in 2000 that was later acquired by Amazon in 2005. The format builds on the PalmDOC/PDB container structure, adding support for HTML-based content markup, embedded images, a DRM layer, and a JavaScript subset for limited interactivity. MOBI files use a record-based database architecture inherited from Palm OS, with a header structure containing metadata like title, author, publisher, and language followed by compressed HTML content records. The format became the foundation of Amazon's early Kindle ecosystem — the original AZW format used on first-generation Kindles was essentially MOBI with Amazon's own DRM wrapper. MOBI supports reflowable text with basic formatting including bold, italic, headings, lists, and tables, as well as internal hyperlinks and a built-in table of contents. One advantage is broad device compatibility: MOBI files are recognized by Kindle devices and apps spanning over a decade of hardware, as well as numerous third-party readers on desktop and mobile platforms. The format's lightweight structure is another strength — even long novels produce compact files that load quickly on modest hardware. While Amazon has since moved to the more capable AZW3/KF8 format for new publishing, MOBI remains widely circulated in existing ebook libraries and continues to be produced by conversion tools like Calibre for maximum Kindle compatibility.

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.
