I don't know why, but my script removes files from my directory when I'm mass renaming. When there's only say 500 files, it renames them all just fine. When there's say 2000+ it messes up somewhere and some files vanish. The or die is not picking anything up so I'm not sure what or where things are going wrong.

Anyone have any pointers? 

opendir(DIR, $dir) || die "can't opendir $dir: $!";
my @files =grep { /\.jpg$/i || /\.gif/i || /\.png/i || /\.bmp/i  || /\
+.jpeg/i} readdir(DIR);
closedir DIR;

foreach my $file (@files)
{
   my $ext;
   $file =~ m/(.[^.]+)$/;
   $ext = $1;

   $cnt++;
    rename $file, "$cnt$ext" or die $!;
    print "$file is now known as $cnt$ext\n";
}

Could it essentially be going too fast and renaming some to "" which causes Windows to delete them? I figured an error would appear somewhere if it failed to rename something.
