Something along the lines of Ashampoo Burning Studio 2009 (free version) would do the trick, with its backup feature spanning multiple discs and somewhat automating the process for you. GFI Backup 2009, also free, is primarily a backup application rather than a burning application, but also fulfills your needs as it can burn its backups to multiple discs.
Hope this helps,
I have a ton of scifi and fantasy and jokes and other pictures in several rather huge files (some are on an external Hard drive) and want to burn them onto CD-Roms to clean out my computer. I tried to do a burn and get an error code that says the file is too large for one CD-ROm. I really do not want to go through and try and break down all the pix into small files. It seems like back an operating system or two, Windows allowed you to burn a file and when one CD-ROM was full, it would ask for another, and so on. Vista doesn't seem to want to do this..or at least I do not know how to do it.
Any suggestions would be helpful. I have a DVD-RW that I use to burn.
