Have you employed any protection that prevents anyone from running the macro in the db or using a shortcut and deleting the files when not wanted? Since you have already converted your macro to code, it's not too much more effort to employ code based protection. Alternately, I guess you can create a macro as suggested (to run code that was a macro) and get a confirmation from the user via a yes/no message box. One way listed in the provided link is the /cmd switch, which I have used in the past.
The more we hear silence, the more we begin to think about our value in this universe.
