disclaimer: never done this. - trigger the update in 4D, to send the message to all connected user (4D code) -- the above trigger starts a timer event/deamon which eventually shuts down the server - in the On Shut Down database method, use LEP to trigger a .bat file which copies the need files. -- the new files will need to be in a specific location, and so will the server replacement files - to trigger the .bat file there are a couple of options (links below) to setup a timed task (probably 2 .bat files one that creates the scheduled task to execute the 2nd to do the actual copy. - in the batch file that does the copy you *should* be able to launch the 4D app again too.
