prevent copy

i just need to prevent a file from being copied from the harddisk to another one or flash or cd
can this be done? :wave:

I don't think so.

You could deny users read access to stop them copying it but that will of course stop them opening it too.

so there is no way to prevent them from copin' the files

You should be able to lock the file in code if you're program was running all the time but I'm going to bail out here and leave it to someone who knows better...
