Hi Barry,
Okay the difference between Audio CD and Data CD.
Audio CDs are like the ones you buy at your local store that come from your
favorite artist. They are playbable in pretty much any CD and DVD player but
are limited to about 80 minutes of music and voice.
The .CDA file you see in Explorer is basically a pointer to where the actual
music lives on the disc, it's not the real music.
Data CDs can contain WMA, MP3, WAV, (and if you have iTunes, M4A, M4P) to
name just a few of the audio file types. There are more that are out there.
Data CDs are great for your car stereo when it supports MP3 and WMA
playback, portable disc players that support MP3 and WMA, DVD players that
support MP3 and WMA, etc. Understand, not all car stereos, portable disc and
DVD players will support those file formats, but as time goes by, more do.
The added advantage is that using these file types with the average file size
being about 4mb, you can put around ten hours of music on a data disc. Audio
CDs 1 hour and 20 minutes, Data CDs 10 hours.
What I would use for burning is based upon what my target use is.
If I'm giving someone a CD with less than 20 or so tracks and I want to make
an album cover for the case, a CD that can be played in pretty much any
device that accepts CD the world over, I'm going to make an audio CD. These
are also great for custom gift CDs.
If I want to have a lot of music on one disc and I know that it's going to
be used in a computer, or a stereo that supports playback of WMA and MP3 type
files, then I'm going to go the Data CD route.
Does this help?

Thank You, that was a very good explanation.
It was what I had thought & this confirms it.
Data is what I wanted to do as I want more music on the CD for use in my RV
which can play MP3.
