About formats

PPSX (PowerPoint Slideshow XML) is the Open XML counterpart to the legacy PPS format, introduced by Microsoft with Office 2007. Like PPTX, a PPSX file is a ZIP archive containing XML parts that describe slides, layouts, themes, and media assets according to the Office Open XML specification. The distinguishing characteristic is behavioral: opening a PPSX file launches the presentation directly in full-screen slideshow mode, bypassing the editing environment. This makes PPSX the preferred format for distributing finalized presentations where the audience should experience the content as a seamless visual narrative without exposure to the editing interface, slide sorter, or speaker notes panel. PPSX files support every visual feature available in PPTX including transitions, animations, embedded video and audio, hyperlinks, SmartArt, charts, and custom slide timings. One advantage is streamlined delivery — a PPSX file attached to an email or shared via a link opens as a polished presentation with a single click, requiring no instruction to the recipient. The XML-based foundation provides another benefit: PPSX files are typically much smaller than equivalent PPS files due to built-in ZIP compression, and their contents can be inspected or modified programmatically using standard XML tools. The format is supported for playback in PowerPoint, LibreOffice Impress, Google Slides (after upload), and various mobile presentation apps, ensuring broad cross-platform reach for distributed slide decks.
Developer: Microsoft
Initial release: January 30, 2007
SNB is a proprietary ebook format developed by Shanghai Nutshell Electronics, a subsidiary of Shanda Interactive Entertainment, for the Bambook e-reader launched in August 2010. The format is structurally based on EPUB principles, packaging HTML content, CSS styling, images, and metadata within a compressed archive, but uses a proprietary container that restricts native playback to Bambook devices and associated software. Shanda designed the Bambook and its SNB ecosystem as an integrated reading platform tied to the Cloudary literature portal (later rebranded as China Literature), one of China's largest online publishing networks hosting millions of web novels and serialized fiction. The format supported reflowable text, chapter navigation, bookmarks, and basic typographic controls suited to Chinese-language content display. One advantage was tight integration with Shanda's massive content catalog, providing readers instant access to an enormous library of Chinese-language literature directly through the device. The Bambook was initially offered at a heavily subsidized price point, using the content ecosystem to drive revenue — a model that preceded similar strategies by other e-reader manufacturers. While the Bambook hardware line was eventually discontinued as the Chinese market shifted toward tablet-based reading apps, SNB files from that era can be converted to standard formats using tools like Calibre with appropriate plugins. The format represents an interesting case study in platform-specific ebook ecosystems within the Chinese digital publishing landscape.
