About formats

CDR is the native file format of CorelDRAW, a vector graphics editor developed by Corel Corporation and first released for Windows in January 1989. The format stores complex vector illustrations using a RIFF-based container structure (Resource Interchange File Format), organizing page content, object properties, color palettes, and metadata across multiple data chunks. CDR supports a comprehensive range of vector objects including Bezier curves, rectangles, ellipses, artistic text, paragraph text, powerclips, drop shadows, transparency lenses, contours, blends, envelopes, and multi-page document layouts. Each new major release of CorelDRAW introduces an updated CDR version, sometimes adding features that are not backward-compatible with older software versions. One notable advantage is rich feature density — CDR files can contain extremely complex artwork combining vector objects with embedded bitmap effects, multi-point color fills, and mesh fills, all within a single native document. The format's strong presence in certain professional niches is another practical strength: sign-making, screen printing, engraving, and vinyl cutting industries widely standardize on CDR as their primary working format, with direct output to cutting plotters and production equipment. While CorelDRAW originated as a Windows application and CDR remains most fully supported on that platform, import support exists in competing editors including Inkscape, Adobe Illustrator, and LibreOffice Draw.

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.
