Hi,
I’m running a winn4.0 platform.I have a folder on a clients computer that I need to backup everyday.He does not leave his computer on overnite, it’s on only during the day.I would like to write a batch file that would do a copy everyday at the same time(5 days a week).I have never written a batch file before.Any help would be appreciated.Is there a website that would give some pointers on this.Thank’s in advance…
