Mike and Vlad and Steve,

I don't think there can be any distinction between the two - local or (file) server.

I spent the day finding and reading on this subject and I've summarized what I found in thread #749598. In essence, for this issue...
VFP will issue the FlushFileBuffers (I presume) and it will be intercepted by the "Network Redirector" if it is for a non-local file. In this case the I/O will be passed to the (file) server for execution, which I assume will include tending to the cache on the local machine.

In summary, VFP cannot and does not make any distinction as to the location of the file in question, and that is by design of the OS. All that VFP does is to issue I/O commands to the LOCAL file system and then the OS does what it has to do, totally transparently to VFP or any other standard application.

So I think my wish is presently well phrased and I plan to leave it as-is unless new information is forthcoming.

cheers

>>Jim, I think you should re-phrase this wish to make it more clear. FLUSH should control caching only for LOCAL computer, where it have control and power to do so. It should not do this for any other kind of storage, because no controlling on the way that storage manages cache and writes.

Client/Server and other networked cases are obviously another matter altogether - a red herring in the context of this wish. Let's not forget that VFP is also a tool for building standalone applications that run locally. The wish, for me, is that FLUSH do what it says in the documentation, what it used to do before things got "advanced". Totally disabling write-caching is rather heavy-handed, and it would be nice not to burden VFP programmers with the intricasies of Window API and version dependencies in such a basic operation.
