About formats

RB is the native ebook format of the Rocket eBook, one of the first commercially available dedicated e-reading devices, developed by NuvoMedia and released in October 1998. Founded by Martin Eberhard and Marc Tarpenning — who later co-founded Tesla Motors — NuvoMedia designed the Rocket eBook as a handheld device with a reflective LCD screen, capable of storing approximately ten books in its internal memory. The RB format packages HTML-based content along with embedded images, metadata, and a table of contents into a single binary container optimized for the device's limited hardware. Content was purchased and downloaded through NuvoMedia's RocketLibrarian desktop software. A notable advantage of the format was its early support for bookmarking, annotation, dictionary lookups, and adjustable font sizing — features now standard on modern e-readers but revolutionary in the late 1990s. The Rocket eBook demonstrated viable commercial demand for dedicated reading devices, paving the way for subsequent platforms from Sony, Amazon, and others. NuvoMedia was acquired by Gemstar-TV Guide International in 2000, which discontinued the device line in 2003. While RB files are largely a historical curiosity today, they can be converted to modern formats using ebook management tools, and the format remains significant as a pioneering chapter in the evolution of digital reading.

POTX (PowerPoint Template XML) is the Open XML template format for Microsoft PowerPoint, introduced with Office 2007. A POTX file is a ZIP archive containing XML parts that define slide masters, slide layouts, theme colors, theme fonts, theme effects, placeholder configurations, and default content — everything needed to establish a consistent visual foundation for new presentations. When applied, a POTX template creates a new PPTX document inheriting the template's complete design system, including multiple slide layout variants (title, content, two-column, comparison, blank, and custom layouts) each with precisely positioned placeholders. The XML-based structure brings advantages over the legacy POT format: templates can be inspected and modified using standard XML tools, design elements are cleanly separated into dedicated files (theme.xml, slideMaster.xml, slideLayout.xml), and built-in ZIP compression yields smaller file sizes. One advantage is design system management — POTX files encapsulate an entire visual identity as a distributable package, and the modular XML structure makes it straightforward to update individual elements like color schemes or font stacks without rebuilding the entire template. Broad compatibility is another strength: POTX templates work in PowerPoint on Windows and macOS, LibreOffice Impress, and online platforms. The format integrates with PowerPoint's template gallery and organizational template libraries, enabling centralized design governance across large teams.
