Convert CBC to RB

The CBC (Comic Book Collection) file extension is a compressed archive format used primarily by the Calibre eBook management application. It consolidates multiple comic book files, typically in CBZ (Comic Book ZIP) and CBR (Comic Book RAR) formats, along with a UTF-8 encoded text file named "comics.txt" that lists the contents. Introduced to streamline the organization and conversion of comic book collections, CBC files facilitate efficient management and conversion to various eBook formats such as EPUB, MOBI, and PDF.

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.
