I would like to add the Win32::API to the Perl which comes with get_iplayer.
Is that possible?

Here is the script I'm trying to run.  It analyses two directories for their
total size and returns an output in a format suitable for MRTG.  Perhaps I
should just substitute Win64 for Win32?  I've only used Win32 before.

Here's the script in case it clarifies things...

# From: http://www.perlmonks.org/?node_id=2311
# and: https://rt.cpan.org/Public/Bug/Display.html?id=61520

# Note that Windows Vista/Server 2008 or later is required for GetTickCount64.
# This version returns bytes, not MB.

use strict;
use Win32::API;
use Sys::Hostname;

my $GetTickCount;
$GetTickCount = Win32::API->new("kernel32", "int GetTickCount64()");
my $uptime;
my $dir1 = '.';
my $dir2 = '.';

if (@ARGV[0] ne "") {
  $dir1 = @ARGV[0];

if (@ARGV[1] ne "") {
  $dir2 = @ARGV[1];

print &dir_tree_size($dir1) . "\n";
print &dir_tree_size($dir2) . "\n";
$uptime = $GetTickCount->Call() / 1000;
printf  "%d day(s)  %dh  %dm\n", int($uptime/86400), int(($uptime/3600)%24),
print "PC " . hostname . "\n";
exit 0;

sub dir_tree_size {
  my $dir = shift;
  my ($i,$total, $f);
  $total = 0;
  opendir DIR, $dir;
  my @files = grep !/^\.\.?$/, readdir DIR;
  for $i (@files) {
    $f = "$dir/$i";
    if(-d $f) {
      $total += dir_tree_size($f) }
    else {
      $total += -s $f}
  return $total;
