They are data, 1s and 0s. They can be read and copied directly, with no conversion involved. The fact that they are presented as files shows that Windows has software in it that can read the file system of an audio CD (whether it's original software or an add-on -- I suspect the former, since Windows was always able to *play* audio CDs). This is no different than use the Finale FILE OPEN dialog and displaying ALL FILES. You'll see non-Finale files that Finale can't do anything with, but Finale can still read the file listing. It's all 1s and 0s. All of it. And nothing needs to be converted to copy those 1s and 0s. However, all file systems use some form of error correction, and non- lossy error correction will produce a result identical to the file that produced the read error. So, there's no loss of fidelity except if the error correction *fails*. If it does, then there will be audible artifacts, like skips, dropouts or pops and clicks. If you don't hear those, then the error correction worked. -- David W.
