Yes, it works. But it's lossy--the resultant file will be degraded, however slightly, from the original. It requires the use of an easily obtained, inexpensive CD-RW. Why not take advantage of the ability, included with every Mac, of Disk Utility to create a virtual CD-RW (or better yet, DVD-RW) to do the file swapping? It would be much faster, and easier on both the disk and the drive mechanism. Easy to use. But, should you need it, no help is available.
