         finfo_close( $finfo );
         echo "$file $real_mime\r\n";
     }
 }
 }}}

 Results:

 recording6021333337014136895.mp3 video/mp4
 SampleAudio_0.7mb.mp3 audio/mpeg
 to_test_on_timby_voice_note.m4a application/octet-stream


 All the files are valid, but `recording6021333337014136895.mp3` and
 `to_test_on_timby_voice_note.m4a ` because of the mime type.
