I'm sure there are dozens of audio CD burning programs that will do the same, but I use iTunes to burn multiple CDs of the audio books my wife downloads. The book will download as a large multi-chapter file too large for a single CD, but iTunes gives you an easy option to burn across multiple CDs. Or, within a Playlist that contains the audio book, I simply select as many chapters that will fit onto a CD and continue until I'm done.
I managed to download an audio book onto my Windows 7 computer. The download is several times too large to load onto one CD, but it will not let me divide it up so that I can put it on several CDs in order to listen to it in my car. Any idea of how to resolve this problem will be greatly appreciated. I have Windows burning capabilites as well as Roxio Creator Home edition. Bob
