Can’t find resource pack in folder after compressing to zip!

So I want to use the faithful texture pack but want to use it with hightlighted ores. So to do this i replaced the ores of the faithful pack in the resource pack folder to highlighted ores of a different resource pack. And after i done this i have a folder but when i put the folder in the resource pack folder minecraft crashes. And if i compress it to a zip file it doesn’t show in game, but only inside the folder I can see it.

A resource pack for Java requires a pack.mcmeta in the root of the zip, and a resource pack for Bedrock requires a manifest.json. See here (Java) or here (Bedrock) for details and examples.
