You are doing a lot of work that can be done with the core File::Find module.

File::Find recurses down a directory tree from a list of starting points. When File::Find enters a directory, it does a readdir(). The output of that can be processed by a user supplied subroutine - could say prune off paths not to follow or sort the names or whatever. Here I just counted the number of simple files (-f) and returned the list of files/directories unchanged.

The wanted() subroutine will be called for each file/directory - but I don't think there is anything to be done in this example, so it does nothing. 

#!/usr/bin/perl -w
use strict;
use File::Find;  # a core module (no installation needed) #

my @root= ("C:/temp");  #an array of starting directories
my %options = (preprocess =>\&new_dir, wanted=>\&wanted);

my $date = localtime;
$date =~ s/\b(\d)\b/0$1/g; #pad single digits with zero
                           #this seemed to be a requirement for some
                           #reason
print "$date\n";

find ( \%options, @root);

sub new_dir
{
   my @files = @_;  # the readdir() output 
                    # contains both (files and directories)
   
   my $num_files = grep{-f}@files; #-f are simple files
   printf "%-5i %s\n", $num_files, $File::Find::dir;
   
   return @files;   #return the list to continue processing
}

sub wanted
{
   # not used here, but dummy sub is needed for syntax
   # this routine is called for each file/directory
   # if we wanted to do something special for each one
   # maybe get a size or whatever...

   # the full path name of this file would be in $File::Find::name 
}
