Since you are printing the directories on the way out you should be able to just do the following:

use strict;
use warnings;
use File::DirWalk;

my $folder = 'E:\test\foldersize\1-folder|E:\test\foldersize\2-folder|
+E:\te
+st\foldersize\5-folder';
my $depth  = 3;

my @directory = grep!/^\s*$/, split/\|/, $folder;

my @folder;
my %dirs;
for my $directory (@directory){
  my $dw = new File::DirWalk;

  $dw->onDirLeave(
    sub {
          my ($dir) = @_;
          if ( !exists $dirs{$dir} ) {
              if(  $dir =~ /(.*)\\/ ) { undef($dirs{$1}); }
               push (@folder, $dir);
          }
          return File::DirWalk::SUCCESS;
       }
     );
                                            
    $dw->setDepth($depth);
    
    $dw->walk($directory);
}

print $_,$/ for @folder

and hence it won't print any directory that has any directories in it.

Are you posting in the right place? Check out Where do I post X? to know for sure.
Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
Want more info? How to link or How to display code and escape characters are good places to start.
