I have around 60 gb in various folders that i want to back up to dvd. (single layer). i am having trouble finding a program that will take the single folder (that contains many many other folders) and split it up across however many discs it would take to fit. i also dont want any of the folders to get broken up in this process. i dont want to waste any disc space and it would take me a very long time to manually set up each disc to burn. anyone got any ideas?
