Hi Monks I have the following snippet of code which creates an MD5 hash of a folder using the Digest::MD5::File module. Ideally I just want to use the Digest::MD5 module but from what I've read it can't MD5 hash a folder. I'm unable to get IT to install the Digest::MD5::File module (slow process of installing and testing software) so how do I go about fixing the bottom piece of code to MD5 hash a folder successfully or can you suggest another way to create a hash of a folders contents using the standard MD5 module.

use Digest::MD5;
use Digest::MD5::File;
.....
$filemd5->addfile($MD5);
        my $md5value = $filemd5->hexdigest();
        push @md5list,"$md5value,$file";
    }
        my $targetmd5 = $p00path . $p00 . '.md5';
        my $MD5 = undef;
        if (not open ($MD5,'>',$targetmd5)) {
            print "Could not open $targetmd5 for write,Error: $!\n";
            next P00;
        }
    my $qcmd5 = Digest::MD5->new(); # Make MD5 Object for checksum
        print $MD5 "# MD5 File for Optical Media ID $p00\n";
        print $MD5 "# ISO created by $name $datestring\n";
        foreach my $line (@md5list) {
            $qcmd5->add($line);
            print $MD5 "$line\n";
        }
        my $folderMD5 = Digest::MD5::File->new;
        $folderMD5->adddir($p00path);
        my $finalmd5 = $folderMD5->hexdigest;
        print $MD5 "CHECKSUM: $finalmd5\n";
        close $MD5;
        print "Made MD5 file for $p00\n";

My previous code below wasn't creating an MD5 hash of the folder it was creating a hash of the path and the item number... 
$filemd5->addfile($MD5);
            my $md5value = $filemd5->hexdigest();
            push @md5list,"$md5value,$file";
        }
    my $targetmd5 = $p00path . $p00 . '.md5';
    my $MD5 = undef;
    if (not open ($MD5,'>',$targetmd5)) {
        print "Could not open $targetmd5 for write,Error: $!\n";
        next P00;
    }
    # Make MD5 Object for checksum
    my $qcmd5 = Digest::MD5->new();
    print $MD5 "# MD5 File for Optical Media ID $p00\n";
    print $MD5 "#\n";
    foreach my $line (@md5list) {
            $qcmd5->add($line);
            print $MD5 "$line\n";
    }
        my $finalmd5 = $qcmd5->hexdigest();
        print $MD5 "CHECKSUM: $finalmd5\n";
