A couple of remarks on top of those of BrowserUK:

1) Perl has an elsif option, so you can simplify you sub thusly:

sub recurseDir2 {
   my @temp = (glob $_[0]);
   foreach (@temp) {
      if (-d $_) {
         print "Directory: $_" , "\n" ;
         recurseDir2("$_/*");   
      }
      elsif (-f $_) {
         print "File: $_ \n";
      }   
   }  
}

2) There might (I'm not sure with Windoze) be some 'things' in your directories meet neither the -f nor the -d test. In which case, I would recommend adding an else clause:

sub recurseDir2 {
   my @temp = (glob $_[0]);
   foreach (@temp) {
      if (-d $_) {
         print "Directory: $_" , "\n" ;
         recurseDir2("$_/*");   
      }
      elsif (-f $_) {
         print "File: $_ \n";
      }
      else {
         next;
      }
   }  
}
