Here is the modified code:

use strict;
use warnings;
use diagnostics;

use Net::FTP;
use Sys::Hostname;
my $hostname = hostname();


my $file = '00000001.610';
my $fileB = '00000002.610';
my $host = $hostname;
my $user = '*******';
my $pass = '*******';
my $dir  = '/doytest/cgi-bin/';
my $ftp  = Net::FTP->new($host, Debug => 1);

$ftp->login($user,$pass);
#$ftp->cwd($dir);

$ftp->get("$file","c:/Temp/$fileB");

$ftp->quit;

This is the message I get after running the script;

But when I look in my C:/Temp folder on my pc, the file isn't there.
