gaf at gaf:~/downloads> unzip SP32158.exe
Archive:  SP32158.exe
  End-of-central-directory signature not found.  Either this file is not
  a zipfile, or it constitutes one disk of a multi-part archive.  In the
  latter case the central directory and zipfile comment will be found on
  the last disk(s) of this archive.
unzip:  cannot find zipfile directory in one of SP32158.exe or
        SP32158.exe.zip, and cannot find SP32158.exe.ZIP, period.
