Thanks again Ken, I have the following code, I do need to work on it a bit, at the moment it's printing out C:\Temp and nothing else. Athanasius code is printing out each of the P00 and I00 directories I made under C:\Temp for testing. I'll check out your example further, thanks 

#!/usr/bin/perl
# dirpathdupes

use strict;
use warnings;
use File::Find;
use Fcntl;
#*****************Path Variables**********************
our $wellpath = 'N:\\repos\\open\\Wells\\Regulated\\';
our $surveypath = 'N:\\repos\\open\\Surveys\\Regulated\\';
our $testpath = 'C:\\Temp\\';
#******************************************************* 

my %dirs;
find(\&dir_names, $testpath);
my @dup_dirs = grep { $dirs{$_} > 1 } keys %dirs;
foreach my $l (@dup_dirs) {
    print "$l\n";
}

sub dir_names
{
    return unless -d;
    return unless /[IPD]\d{8}$/;
    ++$dirs{$File::Find::dir};
