If all you want is to ensure that the DOS file system "knows" about all 
the bytes you've written to the files, you DON'T need to flush the 
caches.  That's because subsequent reads will check the cache first, and 
will find those bytes there even if the actual disk write has been 
delayed.

Only when you are going to reboot, or switch off your machine, you need 
actually to ensure the cache is flushed.
