updating files

[Bev]

I know to some of you this would be simple, but I am lost.
I have multiple programs within many folders on users machines.
these programs range from DOS applications to .net applications.
when there are new versions of these applications, I need to overwrite the existing files on the users machine with new files which are stored in a central location on a server.
I need a .net application that will look are a particular file to exist (we refer to this as a check file) and if the file does not exist then overwrite all existing files with the files on the server.
we do not want to compare the date of the files because depending on applications there may be a need to go backwards to an earlier file.
can anybody tell me how to get started? I know i need to use System.IO.File classes.

Hi Bev,

This method you want to use has a big disadvantage.

If there is an extra dll or whatever created and you are using the way you
do it now, you never get that. (A program that was first in one file and now
in more).

Just my thought.
