About formats

DOTX is the Open XML template format for Microsoft Word, introduced with Office 2007. A DOTX file is a ZIP archive containing XML parts that define document styles, page layout defaults, theme colors, theme fonts, numbering formats, boilerplate content, headers, footers, and other elements that establish a reusable document foundation. When applied, a DOTX template creates a new DOCX document inheriting the template's complete formatting system. The XML-based structure provides advantages over the legacy DOT format: templates can be inspected and modified using standard XML tools, individual components (styles, themes) are cleanly separated into dedicated files, and ZIP compression yields smaller file sizes. One advantage is modular design management — DOTX templates encapsulate a complete formatting identity as a distributable package, and the XML architecture makes it straightforward to update specific elements like color schemes or font definitions without rebuilding the entire template. Broad compatibility is another strength: DOTX templates work in Word on Windows and macOS, LibreOffice Writer, and online platforms including Google Docs (with conversion). The format integrates with Word's template management system and organizational template libraries via SharePoint, enabling centralized document governance across large teams. DOTX has become the standard for distributing document formatting frameworks in corporate, academic, and publishing environments.

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.
