sometimes, certain sound files are treated as system files and cannot be removed. although you don like them or they consume too many disk space, you cannot delete them.

so i made these silent sound files and kept minized in size. they are playable and thus can be recognized, and were trimmed to 0 or 1 sec long with very low bitrate.
