>I can't answer the question for you about whether FLUSH works for local and not network drives, but I understand that it forces the data to be written to the disk. Hopefully, someone will enlighten both of us on this issue.

Presently the customer is checking out the effects this setting will have on the rest of its network (email and other systems) before they will change this setting. I will let you know what happens.

I'm pretty sure the only thing that FLUSH does is empty the VFP buffers to the OS. When the OS actually writes the data to the disk is dependant on it's settings for caching, etc., and may even be under the control of the hardware itself.
