  • FileNameDrop[…,OperatingSystem->"os"] uses the conventions of the specified operating system. Possible choices are "Windows", "MacOSX", and "Unix".
  • FileNameDrop just operates on names of files; it does not actually search for the file specified.
  • If more elements are specified to be dropped than are present, FileNameDrop just drops those that are present.
  • FileNameDrop[File["name"],…] is also supported.
