Burn for example 900MB across two CDs automatically?

Let's say I have three files 300MB each. If I were to drag them into the CD-ROM drive in my Windows XP computer and click Write these files to CD, Windows would complain and spit out the CD. I'm looking for software that would automatically realize This Don't All Fit on one CD and be smart enough to split it onto two. Ideas? Is this a function in one of the big softwares I don't know about?
