>>As part of a complex process, I create a set of DBFs on the fly. (The simple explanation is that they're an intermediate step between an object model and an XML file.) Every now and then, a user gets error 1705: "File access denied" on the CREATE TABLE command for one of these files. Sometimes, it's for the DBF; sometimes, for the FPT.

Bunching these wouldn't work in the relevant context. They're truly generated on the fly, based on what data is in the object model.

Again, this is happening only a tiny, tiny percent of the time. I've never seen it myself, but my clients have seen it occasionally over a long period of time.
