Very helpful Hank. Thanks.

Wonder if there is a way to do the ram disk setup with VFP code so that it is transparent to user.

The reason is that a) we do a lot of queries; and b) VMFS, even in VSphere 5, is slow at big block writes (v5 speeds up small bursts, but doesn't affect the big block writes). We set up 4GB for up to 20 users. For a single user, 500MB seems to be plenty. We do, by default, on app launch delete all tmpfiles files that are not currently locked. A tmpfile not currently in use has no need to exist. :)
