   Not sure if this will help but if a file is locked because it is being   
   written to the following can be used:   
      
   :: _TT is a full file name   
      
   :WriteCheck   
   TIMEOUT 30 > NUL & ::        seconds to wait between checks   
   CALL >>%_TT% > NUL   
   IF ERRORLEVEL 1 GOTO _WriteCheck & ::    File is still locked for recording
