in thread fast count files

You might have issues using wc -l on Windows, unless you have installed it from somewhere like GNU. However it is easy to implement your own in Perl.
Based on BrowserUk's ideas:

use strict; use warnings; my $t=time; # $n = `attrib /s c:\\* | wc -l`; open (my $pipe, '-|', 'attrib /s c:\\*') or die "attrib: $!"; my $n = 0; while (<$pipe>) { $n++ } close $pipe; printf "$n : %.f\n", time()-$t;
Gives: 380366 : 135 on a used space of 297GB.
