Where should I save files outside the Assets folder?

I would like to save some files that I don’t want to include in my Assets folder, but still keep it with my project. Can I just save it outside the assets folder or should I place it in the “Libraries” folder, etc? Any suggestions? Make a new folder? Thanks.

Just create a new folder that is a sibling to Assets. Unity will just ignore it. Whatever you do, don’t put new files into Library as that’s where Unity stores all of its cache files.
