Zip file format for mods?

[kamikazehighland]

I'm trying to edit one file in a mod I downloaded but it's not working. To confirm its the zip file format that's the problem, I unpacked the zip file, packed the folder back into a zip file without making any changes to the contents, and now the mod doesn't work (it did before). I've tried PeaZip, 7zip and just doing it in windows.

I know Stellaris needs a special zip format but I can't find anything about CKII. What do I use to create a working zip file for a mod?

Just unpack the mod into a folder with the same name of zip. Move descriptor.mod to "mod" folder and rename it to match with the folder. Edit that .mod file and change "archive" to "path" and remove .zip from its name. There you got a fully working mod with any changes possible.
