About formats

POT (PowerPoint Template) is the binary template format for Microsoft PowerPoint, using the same OLE2 compound document structure as PPT files. A POT file contains a complete presentation structure — slide masters, color schemes, font definitions, placeholder layouts, background designs, and default formatting — that serves as a reusable foundation for new presentations with consistent branding. When a user creates a new presentation from a POT template, PowerPoint generates a fresh untitled document pre-populated with the template's design elements while leaving the original file unmodified. The format supports all visual features available in PPT including custom slide layouts, embedded graphics, animations, transition presets, and action buttons on master slides. POT templates became central to corporate identity management in organizations that standardized their visual communications through PowerPoint, ensuring every department produced presentations with approved logos, color palettes, fonts, and layouts. One advantage is brand consistency at scale — distributing a POT file across an organization guarantees that all new presentations inherit the correct visual identity without requiring each author to manually replicate design elements. Rapid document creation is another strength: presenters start with professional layouts and focus on content rather than design, reducing preparation time. While the XML-based POTX format has replaced POT for modern workflows, the binary template format remains in use where compatibility with PowerPoint 97-2003 is required.
Developer: Microsoft
Initial release: 1997
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.
