The RB file extension stands for Rocket eBook File, used by the Rocket eBook device from NuvoMedia, introduced in 1998. It is a container format for eBooks, typically holding HTML content and metadata. Although it supports DRM, modern eBooks no longer use this feature. The format includes a unique file structure with specific byte sequences for versioning and content organization.
The MOBI file extension, short for Mobipocket eBook, is a format used for storing digital books. Initially developed by Mobipocket SA, it was designed for mobile devices and eReaders, supporting features like bookmarks, notes, and JavaScript. Amazon acquired Mobipocket in 2005, integrating MOBI into its Kindle ecosystem until 2011 when it was replaced by the Kindle Format 8 (KF8). Despite being deprecated, MOBI files remain compatible with various eReaders and software, ensuring continued accessibility for legacy content.
