The CBZ (Comic Book ZIP Archive) file extension is a format used for digital comic books, consisting of images (typically PNG or JPEG) compressed into a ZIP archive. Developed by David Ayton in the early 2000s, CBZ files organize images into folders representing comic pages and chapters. This format is widely supported by comic book readers, like Comic Book Reader, and can be decompressed using standard ZIP utilities.
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.
