If the file can be accessed by other people, it can be copied. Copying by right clicking is only one way, using the Ctrl/C key combination is another.
What you're trying to do is essentially the same thing as what Microsoft and the RIAA and the FIA are trying to do...stop unauthorized copying, or pirating. Every time they come up with a method, somebody cracks it within, at most, days, usually hours.
The only way to be absolutely, positively sure no one will copy your file is to deny others access to it by encrypting it or passwording it.
