As documented, if pure perl can't extract the archive, the external command line tool is tried instead if available. tar xzf works fine on the file, but produces nothing.

Confirmed by turning debugging on: 

#!/usr/bin/perl
use warnings;
use strict;

use Archive::Extract;

$Archive::Extract::DEBUG = 1;

my $ae = Archive::Extract->new( archive => 'VLF20160618.tgz' );
if ($ae->extract) {
    use Data::Dumper; Dumper($ae->files);

} else {
    warn "ERROR: " . $ae->error;
}
print "Still here\n";
