Professor,

I quess you are nursing your users more than nessasary, would it be to mutch to ask them to save any new projects in the same folder or subfolders under this, like C:\Projects, and then you will guarantee a backup off that folder ?

If you have just one folder to check you could use RoboCopy from the ressource kit

If this is the doings of an application, i would still suggest RoboCopy.

For a RoboCopy-like solution for Win9x, look here;
Using KiXtart to syncronize directories

(This is an old post, could be improved by using newer KiX functions)

If you want an oversight of all folders containing a .DAT file, DirPlus() could me moderated to do that.

What is your objebtive by this task, have I missed something, ore haven’t you described it?
