How burn large folder to span multiple DVDs
Under Mountain Lion, I want to burn a large (roughly 18GB) folder so as to span multiple (double-layer) DVDs.The files are just various kinds of data -- not any particular kind such as audio or video. Is there some way to do this without having to buy some expensive burning app?
