Today I learned that the .cbz file format used for digital comic books is just a zip file full of jpeg images with the extension changed from .zip to .cbz.
I'm definitely going to start using that. Sometimes I zip up a bunch of images, primarily to keep them archived together, and later I want to poke around in the zip file to see if it contains a particular image.
@munroe I'd never heard of that file format, but I can't help but wonder if cbz stands for "comic book zip"?
