        if (Directory.Exists(target.FullName) == false)
        {
            Directory.CreateDirectory(target.FullName);

        foreach (FileInfo fi in source.GetFiles())
        {
            fi.CopyTo(Path.Combine(target.ToString(), fi.Name), true);
        }

        // Copy each subdirectory using recursion.
        foreach (DirectoryInfo diSourceSubDir in source.GetDirectories()) …
