I've read the manual. That's why I said I cannot find anything in the documentation that mentions "Data-Add," or making a DVD disc act like a computer hard drive.
I've formatted DVD-RW discs using UDF but when I try to drag-and-drop files to them, I get an error message saying the disk is full, which is not true because the disc is empty.
I know how to drag-and-drop files from within DVDMF, but the product description says "Make DVDs/CDs act like hard drives - Format your discs with Data-Add to conveniently drag files on and off the disc, just like it was a computer hard drive."
Does anybody know how to do this

Does anybody know what "Data-Add" is
