You can make new folders with:

	'mkdir'

i.e.

	mkdir("Macintosh HD:New Folder",0755)

(the '0755' is a UNIX file mode; think of it as a magic number and don't
worry too much about what it actually means).

To create a file, do something like:

	$myfile = "Macintosh HD:New Folder:MyFile.txt";
	open(OUT,">$myfile") ||
	    die "can't open '$myfile' for output: $!";
	print OUT "Hello world\n";
	close(OUT);

The key ingredient is the '>' that comes before the filename, which tells
Perl that you want to open an output stream.

All this is covered in simple and friendly fashion in "Programming Perl" by
Wall, Christiansen & Schwartz, pub. O'Reilly, colloquially known as "The
Blue Camel" (for reasons that will become obvious). For a very large number
of Perl-related questions (including basic ones such as this), this book is
the FM that you need to R and will often tell you everything you need to
know. Don't start the interpreter without it, as they say.
