    // Check if container extraction is supported
    if (attachments == null)
    {
        Console.WriteLine("Container extraction isn't supported");
    }
    // Iterate over attachments
    foreach (ContainerItem item in attachments)
    {
        // Detect the file type
        Options.FileType fileType = item.DetectFileType(Options.FileTypeDetectionMode.Default);

        // Print the name and file type
        Console.WriteLine(string.Format("{0}: {1}", item.Name, fileType));
