Audio that use to play wont anymre. Whats wrong?

[UmmAddan]

i had some recording on my nokia phone (audio). i uploaded them onto the computer about a year ago. they worked fine. I THINK they were wav file but im not entirely sure. my computer was going to the shops to get fixed so i downloaded all the files onto a CD. now 8 months down the line i looked at my cd and they are all WMPFile. what is this? i cant listen to them or anything. i got a new computer now s i dont know what happened. (see pic below). one file works but the rest dont. is there ANY way of saving them as i cant lose them. PLEASE.

BTW i have mediainfo and on that it says:
AMR: 98.4 KiB
1 Audio Stream AMR

the mobile i recorded and uploaded from was a nokia 6230i.
