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.

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).
