Nope, nor do Microsoft tell you about all the crud they write to
the registry or about the "hidden" files they use in the C:\ root
directory. Every OS uses hidden or special files to do its job,
provided the ordinary user doesn't uncover the gory details thats
fine.

BTW You do realise that Mac OS X applications are actually
folders and not really the simple files that finder displays
don't you?! :-)

You could skip all files that begin with.
if name[0] == '.' and filter all hidden files.

What makes you think it would be any different? listdir will still
show hidden files there too, its not the OS its the way the function
is defined to work.
