k3b and create image

[JD]

I used k3b to copy the image of an audio cd.
It produced files like
Track01.wav
....
Track16.wav

and it also produced a file simply with the title of the audio cd,
and without extensions and it is 803066400 bytes large.
Running
$ file 'Into The Unknown'
Into The Unknown: data

The file is quite larger than the 704MB max (with overburn)
that a CD can hold. This file is 100MB larger than that.

So, how can I use this file? I was hoping it would be in
a format that could be used by any of the plethora of
media players in linux.
mplayer failed to open it.
