list( $wrapper, $path ) = explode( '://', $path, 2 );
$wrapper .= '://';
}
// Standardise all paths to use /
$path = str_replace( '\\', '/', $path );
// Replace multiple slashes down to a singular, allowing for network shares having two slashes.
$path = preg_replace( '|(?<=.)/+|', '/', $path );
// Windows paths should uppercase the drive letter
