Thank you so very much to everyone who replied. Your replies were almost all very excellent, and would have been helpful, except that I finally figured out that I had a programming error. I was continually creating the file during the macro. So even though M.E. was actually deleting the file, it kept appearing. I should have realized that Insight Software, being such amazing engineers, would have tested M.E. thoroughly. I should have had more trust.
Thanks again to all. I will try to delete this thread, if possible, to avoid confusion to others.
