Just add && !file_exists($filename)

private function validateURLScheme(string $filename) : bool
{
	$allowed_schemes = ['ftp', 'ftps', 'http', 'https'];
	$url = parse_url($filename);
	if ($url && isset($url['scheme']) && !in_array($url['scheme'], $allowed_schemes) && !file_exists($filename)) {
		return false;
	}
	
	return true;
}
