You may want to try a widget like the <a href="http://search.cpan.org/~srezic/Tk-804.029/pod/DirTree.pod" rel="nofollow">Tk::DirTree widget</a>.

<pre><code>#!/usr/bin/perl
use strict;
use warnings;

use Tk;
use Tk::DirTree;

my $mw = MainWindow-&gt;new;
$mw-&gt;title("Type path of directory and click OK");
$mw-&gt;geometry('400x300+'.int(($mw-&gt;screenwidth-400)/2).'+'.int(($mw-&gt;screenheight-300)/2));

my $dir = $mw-&gt;Entry( -text =&gt; '',
 -width =&gt; 20, 
 -font =&gt; 'Courier 12 bold',
 -background =&gt; 'Orange',
)-&gt;pack( -ipadx =&gt; 35 );

$dir-&gt;focus();

$mw-&gt;Button( -text =&gt; 'Ok',
 -font =&gt; 'Courier 12 bold',
 -background =&gt; 'Orange',
 -command =&gt; sub{ dirwindow($dir) },
 )-&gt;pack( -side =&gt; 'left',
 -ipadx =&gt; 40
);

$mw-&gt;Button( -text =&gt; 'Exit',
 -font =&gt; 'Courier 12 bold',
 -background =&gt; 'Orange',
 -command =&gt; sub { exit }
 )-&gt;pack( -side =&gt; 'right',
 -ipadx =&gt; 40
);

MainLoop;

sub dirwindow {
 my $d = shift;
 my $dir_val = $d-&gt;get;
 my $dl = $mw-&gt;DirTree(-directory =&gt; $dir_val)-&gt;pack(-fill =&gt; 'both', -expand =&gt; 1);

You might make a system call to the command line process that opens the file browser. On windows this is apparently the <code>start</code> command, on Linux something like <code>gnome-open</code> or <code>nautilus</code> would work. 

<pre><code>sub open_directory {
 my $directory = shift;

 if ($^O eq 'MSWin32') {
 exec "start $directory";
 } elsif ($^O = 'linux') {
 exec "gnome-open $directory" or
 exec "kde-open $directory";
 # test for more OS cases
 } else {
 die "cannot open folder on your system: $^O";
 }
} 
</code></pre>

Say we are having entry box and a button. When user press the button, it should take path from entry box and open the corresponding folder. How can I do it using Perl/TK? Thanks in advance
