What is RB (RocketBook)?
RB (RocketBook) is a proprietary ebook format developed for the Rocket eBook reader, one of the first dedicated e-readers launched in the late 1990s. This format supported basic formatting, hyperlinks, and images while optimizing content display for the Rocket eBook's screen specifications.
RB files represent an important historical milestone in ebook development, bridging the gap between early personal digital assistants and modern e-readers. Though the format is now obsolete with the discontinuation of Rocket eBook devices, it established many conventions later adopted by mainstream ebook formats. Supported extension is .rb.
How to open RB?
Opening RB files today is challenging as the original Rocket eBook Reader software is no longer maintained and was designed for older operating systems. No modern e-readers or applications provide native support for this legacy format.
The most effective approach to accessing RB content is through conversion. Specialized software like Calibre with appropriate plugins can convert RB files to contemporary formats like EPUB or MOBI, though some formatting features may not transfer perfectly due to the format's age and proprietary nature.
RB is Developed by: NuvoMedia
RB was Released on: 1998
