In these 3x places, specific arguments like -al or -alR are being used when ftp_rawlist is being called.

I believe, depending on the FTP server settings, they cause trouble -> directories/files can not be listed and ftp_rawlist simply returns empty list.

Here is the code that does not list the files on the server (Hermes Germany carrier FTP - used by a lot of vendors of course) we use:

$adapter = new FtpAdapter($dir, $host, array(
    'port'     => 21,
    'username' => $user,
    'password' => $pass,
    'passive'  => false,
    'create'   => false,
    'mode'     => FTP_BINARY,
    'ssl'      => false,
));
$filesystem = new Filesystem($adapter);
var_dump($filesystem->keys());

And here is the native code which works as expected:

$connection = ftp_connect($host);

ftp_login($connection, $user, $pass);

var_dump(ftp_rawlist($connection, $dir));
// var_dump(ftp_rawlist($connection, '-alR ' . $dir)); // This is how Gaufrette does it

ftp_close($connection);

I believe this arguments must be configurable to resolve mentioned issue - they should be enabled by default to ensure backward compatibility but with an option to disable them.
