You can just change .zip to .cbz either manually via a filebrowser or a script (cbz are essentially just zips).

I think .cbz can only contain images, no subfolders, so maybe you need to make a .cbz per chapter or do a lot of remaming to be able to put them in one directory.

Cbr is the same but for .rar files (which are not open source?).

I think there is a program for adding metadata to manga like Comictagger (which does not work too well for manga) but I can't remember the name ...

It’s just a zip file with a different file extension. Zip a stack of jpegs with filenames that will list them in reading order when sorted alphabetically and then change the extension.

that’s all CBZ is – a set of image files zipped up and the file extension changed to *.cbz (CBR is the same thing but RAR compressed and *.cbr file extension)

Sure! So, “.cbz” and “.cbr” files are literally just a folder of images in zip or rar files respectively, with the file extension changed so they will open in a comic reading app instead of being unzipped/unrared when you click on them. So as long as the filenames of the zipped images are in the correct alphabetical order, all you have to do is change the “.zip” at the end of the filename to “.cbz” (or “.rar” to “.cbr”).

All of you guys are dope !! Thanks for your help
