how do I know what a file really is after the command 'file' output "data" ?
 

Hi, everybody !

I download some movies those are with 'mkv' , but couldn't be played, I tried other players , like mplayer , dragon , xine, even swich OS to windows , didn't work . not all of those files , but some of them. one of them named 'the.other.man', 2GB.
I opened a terminal and executed "file the.other.man.mkv ", output is "data", and command 'strings the.other.man.mkv", output like as follow:
