I've used robocopy + task scheduler before actually for this use case but as far as I could tell robocopy doesn't have a way to search across directories to find files but rather just gets set up on a particular directory. Maybe something in Powershell to find the files and then copy them into a folder which is then set up with Robocopy? Note, I have no access to the computer itself and the users are incapable of doing much beyond downloading a .exe file and installing a program, so whatever is done has to be as close to simple as that for them.
