    Answer: No. If the directory is available in read mode, and users are
    allowed to view the contents of files in the directory, there is no way
    you can prevent copying of data from that directory, or even if you
    could, there is no way to prevent a user from simply opening the
    document and saving it someplace else.

    Once you give someone access to read the content, you give up the
    ability to control what they do with that content, unless you also
    control (totally) the environment/platform in which they read that
    content. But even then it would be extremely difficult.
