Question Folder vs Direct references?

I've organized my project into pretty big hierarchies of things. Like characters, abilities, items, etc.

I've been able to add the entire folder and see all the items under the directory show up, and I've been able to retrieve the assets by label out of the addressables system.

Should I add the root level folder as an addressable or should I be adding each individual file in the directories as an addressable?

It works in the editor, but will the folder work at runtime? And if so, is there a performance impact one way vs the other? Or a download size impact?

I apologize if this is obvious, but I can't find anything about it clearly spelled out in the documentation

 

Don't think it would make any big difference other than maybe a slightly bigger catalog file size due to bigger addresses.
