Media module provides a generic.png file that it copies into /sites/default/media-icons/generic. That file is used on my site ~300 times, but I'd like to replace it with another PNG. Is it possible to replace the actual file that is associated with that file entity? Ideally I'd keep the generic.png name, but I can use an updated file name if needed.
I've tried simply replacing the file in /sites/default but that had no effect.
