Well many programs write stuff to the system registery, and those entries stay around forever, and maybe windows is suppose to work that way. I am wanting to write a shareware program (with a low registration fee) with the idea that the user can run it 100 times before the rating of the thing would start to become very limited. So how do I keep people from just re-installing the software and running it 100 new times? I need to be able to put information someplace that isn't going to go away if the user deletes the software. (Have a 100 run limit isn't going to be much use if the user can easily defeat the mechanism.) I can put information in the system registery, but a clever user can use regedit to delete that information. So I need a backup someplace. My intentions were to do exactly what you have suggested should be a hanging offense. I was going to put files in \windows and \windows\system. I could make the files hidden. The net harm in this is nothing. The extra files might cost 8K. (Hard disk space is about 3 cents a meg.) My plans are to write both a chess playing program and a database. I already have the database written, but I need a windows interface, which I am going to start working on soon. John Coffey
