First - if you're doing this for a learning exercise, that's fine. But, using File::Find is NOT "stealing code". It is using well-tested and well-written solutions to common problems. I hope you wouldn't think you'd have to rewrite CGI, DBI, or XML::Parser because you'd be "stealing code".

That said, you have a few "issues" with your code. Try the following:

use File::Spec;
 
my $dir = "C:\";
 
sub recurseDir2
{
   foreach (glob shift)
   {
      if (-d)
      {
         print "Directory: '$_'\n" ;
         recurseDir2(File::Spec->catfile($_, '*'));
         next;
      }
 
      if (-f)
      {
         print "File: '$_'\n";
      }
   }
}
recurseDir2($dir)

I wasn't able to reproduce your problem, but I think I know where it might have come from. You're on a Windows system, but using the Unix directory syntax. This is why modules exist, to make sure you don't get screwed up. File::Spec will make sure you use the right directory separator for your system. This isn't "stealing code" - this is intelligent re-use of well-thought out solutions.
