Convert CBC to TCR

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 TCR file extension stands for Text Compressed for Readability, originally used by Psion Series 3 palmtop devices in the early 1990s. It stores eBooks in a proprietary format that offers better compression than PalmDOC, making it suitable for the limited storage of handheld devices. Despite the discontinuation of Psion devices, TCR files can still be read using modern eReaders like Sumatra PDF.
