Yes, there's a lot of that :-) But more precisely, in UNIX systems there's a utility called C, which recognizes data files based on their contents (usually their first few bytes). For this to work, -a certain file called "magic" needs to taught about the "signature" +a certain file called F needs to taught about the I of the data.
