I recently copied some songs from my friend's CD

I checked before copying, CD was playing on my PC

After copying, found songs are not playing on my PC

All songs has 'cda' as file extension

I have Window Media Player, Quick Time Player and VLC Media Player

I am unable to play with any above mention program

How I can convert cda file to wmv or avi file ?

I tried google, but no free download software available

Any suggestion ?
