This sounds like it could be pretty fun! Though for it I'd probably do something like, there's folders in the games, well, folder where the .exe and mod folder is. Inside that folder is a few more, so for example one that's called SFW, one NSFW, one Meme's and one NSFW (NTR Focus). Whatever images, videos or audios you put in them, Byte, or potentially even other actors, could do a little pretend animation of opening that folder, opening one of those files, causing it to appear/play, and Byte, alongside potentially other actors, would have dialogue based on what folder it had been in, then you could close it by just clicking it like the normal pop-ups that happen.
That way it's done in a way that doesn't actually interact with your folders and files, but just looks like it does, as if I'm remembering correctly the Dev's mentioned somewhere, can't remember where, about wanting to avoid having actual capability for interacting with the player's actual folders and files, in a want to avoid potentially malicious mods and the like. I could be entirely misremembering though, or even be outright incorrect lmao.
