Hi Rex,

The javadoc explains this pretty well:

"rws" - Open for reading and writing, as with "rw", and also require that every update to the file's content or metadata be written synchronously to the underlying storage device.

"rwd" -Open for reading and writing, as with "rw", and also require that every update to the file's content be written synchronously to the underlying storage device.


Note that "metadata" here refers to file system properties associated with the file, e.g. last access time, last modification time.
