I have a script that will accept user directory paths as input, and then output the size of every user's folder. Everything was working fine until the script hit a user that had a folder with over 20 identical subfolders. The folder names were identical with 8 characters and in caps: "STUFFCOM". When the script hit this, it ended and reported the following: Can't cd to \\server\d$\dept\users\r_johnson/STUFFCOM/STUFFCOM/STUFFCOM/STUFFCOM/STUFFCOM/STUFFCOM/STUFFCOM/STUFFCOM/STUFFCOM/STUFFCOM/STUFFCOM/STUFFCOM/STUFFCOM/STUFFCOM/STUFFCOM/STUFFCOM/STUFFCOM/STUFFCOM/STUFFCOM/STUFFCOM/STUFFCOM/STUFFCOM../../../../../../../../../../../../../../../../../../../../../.. at C:/Perl/lib/File/Find.pm line 535, <IN> line 1. I have figured a way around this, and that was to reduce the number of subfolders to 19. My question is why would I be receiving this error, and why does reducing the number of subfolders fix the problem? Here is the code for my program:

#!/usr/bin/perl

use File::Find;
use strict;
use Time::localtime;
use File::Spec;

my $cur = File::Spec->curdir;
my $up  = File::Spec->updir; 
my $dirtot;


my ($dir, @parts, $error, $starttime, $runtime, $endtime, $runmin, $ye
+ar, $month, $day, $tm, $date,$rootdir,$userdir,$slash);

$tm = localtime;
$year = $tm->year+1900;
$month = $tm->mon+1;
$day = $tm->mday;
$date = "$month-$day-$year";
$slash = "//";

#Opens the input and output files
open(IN, "< websize_input.txt") or die("Couldn't open websize_input.tx
+t\n"); 
open(OUT, "> websize_out.csv") or die("Couldn't open websize_output.cs
+v\n");

#Separates the newline delimited rows
chomp ( @parts = <IN> );

#Used to calculate how long the program took to run
$starttime = (time);        
                

#Prints headings
print OUT "Path,User,MB,Date,Error?\n";


#Displays total for subdirectories
foreach my $start (@parts) {
  my @dirs = &find_subdirs($start);
  foreach my $dir (@dirs) {          
     ($rootdir,$userdir) = split /$slash/,$dir;
     print "\tWalking $dir\n";
     my $total = 0;
     find sub { $total += -s }, $dir;
     $dirtot = $dirtot + $total;            #Used for determining tota
+l directory size
     $total = ($total / 1024) / 1024;        #Converts to MB
     $total = sprintf("%0.2f", $total);        #Formats output to 2 de
+cimals
     print OUT"$rootdir,$userdir,$total,$date,$!\n";
  }
  $dirtot = ($dirtot / 1024) / 1024;        #Converts to MB
  $dirtot = sprintf("%0.2f", $dirtot);        #Formats total to 2 deci
+mals
  print STDERR "$start: No subdirectories\n" unless @dirs;
}
print "\nOutput created.";


sub find_subdirs {
  my $start = shift;
  unless(opendir(D, $start)) {
     warn "$start: $!\n";
     next;
     }
  my @dirs =
     map {
         -d "$start/$_" &&
        !-l "$start/$_" &&
        $_ ne $cur && $_ ne $up
           ? "$start//$_" : ()
         }    
     readdir(D);
  closedir(D);
  @dirs;
}
