It doesn't belong anywhere, but gets probably restored from a backup of the
NVidia installer. Anyway, that seems to be a common and repeating problem for
more users frequently "zypper dup'ing" TW along with reinstalling the NVidia
proprietary drivers, not just for me. Isn't there a common approach how to
easily clean up old backups? Maybe rather an issue to the NVidia developers...
