in reply to filtering hidden files on Win32

Same basic code... just a few tweaks here and there to get the constant working.

#!perl -w
use strict;
use Cwd;
use Win32::File;

my $attribs;
my $dir = cwd();
print $dir,$/;

opendir( DIR, $dir ) or die "Couldn't open $main::DIR: $!\n";
my @vis_files =  grep { -f $dir.'/'.$_  and
  Win32::File::GetAttributes($_,  $attribs) and
  !($attribs & HIDDEN) } readdir(DIR);
closedir( DIR ) or warn "Couldn't close $main::DIR: $!\n";
print $_, $/ for @vis_files;

    When writing a fire-and-forget duplicates finder just now, I found this thread very useful. My coding style and approach seems rather different though. But whether low code granularity is good is often a highly debated issue. 
    sub dfind {
    my ($dref, $top) = @_;
    hidden( $top )
      and return;
    if (-d $top) {
        for my $file (glob( "$top/*" )) {
            dfind( $dref, $file );
        }
    }
    else {
        register( $dref, $top ); # add to HoA
    }
}

sub hidden {
    my $file = shift;
    my $attribs;
    Win32::File::GetAttributes($file,  $attribs);
    return $attribs & HIDDEN;
}

    Update: note that hidden directories and files are both filtered out owing to how the recursion is contructed.
