you are absolutly right! :o), sorry if did not read you sooner
I have been working on some code, as far as now it show me only on /cgi-bin/ folder the file I want, but I like to change it to something like a server folder but for know just C:/files/err folder for now, I can display it on the Firefox browser, but if I click a link to the file is giving me an error, but i want a dialog to say if you open it or save it to disk. heres the code :

#!c:/perl/bin/perl.exe

use strict;
use CGI;

my $list = new CGI;

my $fileDir = "./";
my @files;

opendir DIR, "$fileDir" or die "Can't open $fileDir $!";
    @files = grep { /\.(?:txt|err|csv)$/i } readdir DIR;
closedir DIR;

print $list->header("text/html"),
      $list->start_html("Archivos in $fileDir"),
      $list->p("Estos son los archivos de $fileDir");

foreach my $file (@files) {
    print $list->p(
            $list->a({-href=>$file},
            $file)
            );
    
}

print $list->end_html;
