>We have had some interesting security concerns come up from our clients recently. We run with a VFP backend and in one case we had a client delete a folder with all of our data files. We have also had Auditors cite our clients because of the ease at modifying dbf files. Any thoughts on how to improve file security (short of going to SQL server, I'm too old for that)?

Is this client on a network? If so what kind? It sounds like someone needs to setup user rights a little better. As for the dbf files - if they can't get to them they can't modify them - or perhaps encrypt all the data in the tables.
