Side bus file

[MoonlightVigil8]

Since the name convention of having a second file to hold the metadata of a file is called side car file, i say that the name of the way tag studio handles metadata with a single file with all of the metadata of the folder should be called sidebus file

TagStudio stores all of the metadata in a database file, which is conventionally called.. a database file. There's no reason to go against that convention and make up a completely new one for the sake of a joke.
