I'm trying to print all the files and directories within a directory(including files and directories in subdirectories. this is my code;

 use strict;
use warnings;
use Data::Dumper;


my $dir = 'C:\Users\test\Dropbox\Perl';
print_rec($dir);


sub print_rec {

    opendir DIR, shift;
    while( readdir(DIR) )
    {
        if(!/\.|\.\./ && -d $_)
        {
            print "$_ is a directory\n";
            return print_rec($_);            
        }
        elsif (!-d) { print "$_ \n"; }
    }
}

My program stops after the it reaches the first deepest level, actually it not returns at the previous level. What am i doing wrong. Understanding this will help me understand how the stack trace works in perl. Thanks !!
