Hi, thank you for the help. I am not completely sure what your code is does, but the 

next if $entry eq '.';
next if $entry eq '..';

did help. I have combined your code with something of another user to come up with this:

#!/usr/bin/perl -w

use strict;
use warnings;

open (Output, ">Output.txt") or die "Can't open";

my $tmp_dir= 'C:\Users\ZB\Desktop\Text Files';
opendir (DIR, $tmp_dir) or die $!;

while (my $file_name = readdir(DIR))
{
    next if $file_name eq '.';
    next if $file_name eq '..';
    print "$file_name\n";
}

close (Output)
closedir(DIR);

All it does is print all the file names in my directory as output(so at least I am on the right path). However I want to iterate through each text file and do some basic calculations(all in 1 sub) within each file. Any ideas?
