Burn Directory to DVD+R

Burn the contents of a directory to a blank DVD+R disc.

Source Directory

The sample code in this article assumes a directory named DataDisc exists under your user home directory. To create the DataDisc directory follow the steps listed in the Source Directory article.

Code

The following function takes a Device object and path to a directory and burns the contents of the directory to a blank DVD+R disc.

private static void BurnDirToDVDPlusR(Device device, string sourceDirectory)
{
    if (!CheckDeviceAndMedia(device))
    {
        Console.WriteLine("Please insert a blank DVD+R in burner and try again.");

        // media is not DVD+R, or is not blank
        device.Eject(true, true);

        return;
    }

    // Use DataDisc to burn the DVD image layout
    using (var dataDisc = new DataDisc())
    {
        // set device, and write method
        dataDisc.Device = device;

        // WriteMethod.DvdIncremental method is recommended for data 
        dataDisc.WriteMethod = WriteMethod.DvdIncremental;

        // close the disc for true playback compatibility
        // this will result in slower disc burning
        dataDisc.CloseDisc = true;

        // DataDisc needs this to create the correct disc image
        dataDisc.ImageType = ImageType.Udf;

        // set volume label and creation date
        dataDisc.UdfVolumeProps.VolumeLabel = "DATADVDPLUS";
        dataDisc.UdfVolumeProps.CreationTime = DateTime.Now;

        // set the image layout from the source directory
        dataDisc.SetImageLayoutFromFolder(sourceDirectory);

        // this may take some time
        dataDisc.WriteToDisc(true);
    }
}
