It would be interesting to see how much faster the win/dos "tree" utility is than the File::Find module (or any of its relatives on CPAN). I know that in unix, File::Find takes much longer than the standard "find" utility for a directory tree of any considerable size.

The only problem with the OP code is that you have to remember to run "tree" yourself -- and save its output in a specific file whose name is hard-coded in your perl script -- before running the script, so that you know your file list is up-to-date. But that's unnecessary -- just run "tree" inside the perl script (it'll still run just as fast): 

my $music_path = ".\\music";  # probably should make this an absolute 
+path...

open my $fh, "D:\\tree /f /a $music_path |"
    or die "cannot run tree on $music_path: $!";

while ( <$fh> ) {
   # everything else stays the same...
}

Actually, it might also be interesting to see whether a win/dos port of the unix "find" utility is slower or faster than "tree"...
