There is no real way to protect from within the application. If you're storing these files on a file system, they will be accesible based on file system permissions. You could store information in a password protected database or something similiar in order to make it only accessible to the application.

Actually on second thought, you may be able to save these files within a resource bundle. I'm not sure if that is entirely protected though.

You can set the read only attribute. It is only a minor inconvenience to someone who wants to edit a file, but you haven't got much control over what a user does outside of your program. At least if a user clears the read only attribute and changes your file you can blame them for it.

System.IO.File.SetAttributes("path\\file", FileAttributes.ReadOnly)

Are you just reading from these files or writing to them? If you're just reading them, you might embed them as resources in your compiled output rather than keeping them as files on disk.
