.CBZ File Extension

Comic book file format that contains images organized into pages; saved as a compressed archive using .ZIP compression; similar to a .CBR file, which uses .RAR compression.

CBZ files can be read using a comic book viewer like FFView (Mac) or CDisplay (Windows). They can also be decompressed using a file decompression utility, which will extract the individual images from the archive, but may not display them in the correct order
