>Marc, we use 'COPY FILE' inside VFP to copy the file to the C: drive, so the copy is complete before the program continues and tries to start it. When we're upgrading the EXE, we add a file 'LOCK.TXT' to the folder. When present, the Wrapper program doesn't check dates/times or copy a new EXE. It DOES warn the user that a new EXE is being uploaded, and suggests they wait a few minutes and try again. They can continue with their present C: drive version if they wish.

Thanks. Must have repressed copy file after a bad experience with it. :)
