Lync recording does not play

Hi there,

I tried to record a meeting using Microsoft Lync 2013. The file was moved from its default location to a different computer but it could not play. I tried to play it again in the original location but it does not play in any media player. 

I have a backup of the recorded file. Could someone help me in how recorded file can be played back?

Many thanks for your kind assistance.
