Hello, I am a newbie. I have a data DVD with total file size of approximately 7.9 GB which I'd like to burn onto two DVDs of 4.7GB (I don't have a dual layer burner). Is it possible to do that with ImgBurn? I tried it several times, but it didn't work out... If it's not possible with ImgBurn, does somebody know how to do that in another way or where to find more information about it? Thanks for your time and your help.
