How Should I Organize Downloaded Licensed Game Models?

[titleknown]

Heya, I use a lot of models from here in my TinkerCAD work to make stuff, and I try to keep them organized by company. And, out of curiosity, I was wondering, in terms of who actually "owns" the models to games licensed from pre-existing properties, would it make more sense to organize them by what company owns the license (Disney, Nickelodeon, ect) or what company produced the games (THQ, EA, Acclaim, ect)?

I mean, I know it'll probably not protect me in the slightest legally because fair use isn't worth a damn in this country, but it'd be a comfort to know at least in terms of filing things properly.
