I just started messing with OneTrainer so forgive my dumb question. Do I need ALL the files from pic related in addition to the actual checkpoint or is there a specific file that I should get instead?

I ask because if I point OneTrainer to just the base model by itself, it does not work. But if I point it to the same file from within a folder that houses all those files, it works. I want to know what file/folder is allowing me to proceed so I don't have to download everything if I don't have to.
