It might be even easier to use

  \InputIfFileExists{filename}{then part}{else part}

If filename exists, this commands loads it and executes the {then part}
(which you coul probably even leave empty), if it doesn't exists it executes
the {else part} (which again you can probably leave empty). See
Appendix A.4of the LaTeX Companion by Mittelback et al. (which is
where I got my info).
