This exactly. I’m not kidding when I say that cbz files are literally just renamed zips. It’s a pretty common technique in software development. Take a zip file, since most things can read and write zips easily, and then just rename it. Even I used it once.
Similarly, cbz is actually a family of file formats:
- cbz → zip
- cbr → rar
- crt → tar
- cb7 → 7z
- cba → ace
