I've used ImgBurn for video but never for data. I want to archive 20 gig of .pdf and .xls data from a project that just ended. 20 years ago when I had too much data for one disk, my Mac would fill the first disk, eject it and say, "Please insert a blank disk." Does ImgBurn on a Vista computer work like that, or do I have to figure out how to put the files on the disks and burn each one as one separate project?
