I'm burning a huge 15GB set of files for some soldiers overseas but for the life of me I can't find out how to allow the burn to continue to a new disk instead of saying it wont fit on just one.
Can you break up that set of files on to multiple disks? or is it just one file and you need to split it?
You could also try compressing those files with a program called WinRAR. Just make sure the soldiers have WinRAR installed over there too so they can decompress them.
I've used that for shrinking 900MB of files into 300MB.
Disc spanning for DVDs probably won't work very well, so unfortunately, you will have to use something like WinRAR to break up the data into DL DVD-sized parts.
