Extension method for changing an enumeration value

I am a little new to extensions. I looked at the existing answer before posting it, because I do not like to write, but I did not see anything that was useful to me.

I want to have an extension method for an enumeration with the Flag attribute that I can call to basically add another enum / flag to the calling enumeration.

Before someone ran this on Int32.MinValue, I really looked enough, but all I found was a bunch of questions for "IsFlagSo-andSet" and flag handling, but not just adding a flag.

I defined the listing as follows:

    [Flags]
    internal enum eDiskFormat
    {
        None        = 0x00,

        _3D         = 0x01,

        Blu_ray_3D  = 0x02,

        Blu_ray     = 0x04,

        DigitalCopy = 0x08,

        Dvd         = 0x10

    }

The extension has been defined as:

    internal static void AddFormat(this Movie.eDiskFormat target, Movie.eDiskFormat newFormat)
    {
        target |= newFormat;
    }

, , Movie.eDiskFormat.Blu_ray... ( eDiskFormat.None).

m.DiskFormat.AddFormat(Movie.eDiskFormat.Blu_ray);

eDiskFormat.None. , "this" , , , , . , , ... , , ; , .

internal static Movie.eDiskFormat AddFormat(this Movie.eDiskFormat target, 
                                                 Movie.eDiskFormat newFormat)   
{   
    return target | newFormat;   
}
