<p>‘Private’ uploaded files (PDFs, images, etc.) will normally be only included in private posts and pages.  But the files themselves can still be accessed by anyone if they know the corresponding URLs.</p>
<p>For example, a PDF file’s URL might be</p>
<pre><code>http://example.com/wp-content/uploads/minutes-20160924.pdf
</code></pre>
<p>and anyone could download that file because WordPress does not get a chance to check their authorisation.</p>
<p>The solution that the Private Uploads plugin uses involves moving any private files to a separate folder, and then configuring the web server to ask WordPress to authenticate access to files in that folder.</p>
<p>So the file’s URL might now be</p>
<pre><code>http://example.com/wp-content/uploads/private/minutes-20160924.pdf
</code></pre>
<p>and an HTTP server rewrite rule will convert this to</p>
<pre><code>http://example.com/?pucd-folder=private&pucd-file=minutes-20160924.pdf
</code></pre>
<p>The Private Uploads plugin will intercept that URL and reject it with a 403 status code.</p>
<p>This plugin is more efficient than some similar ones because it only has to run when serving files in the private folder(s): the web server handles other uploaded files (ones not in the private folders) directly.</p>
<h3>Requirements</h3>
<ul>
<li>Sufficient access to the web server to allow the required configuration.</li>
</ul>
<h3>Acknowledgements</h3>
<ul>
<li>This plugin was inspired by a discussion on <a href="https://wordpress.stackexchange.com/questions/37144/how-to-protect-uploads-if-user-is-not-logged-in" rel="nofollow ugc">StackExchange</a>.</li>
</ul>
<h3>Future Plans</h3>
<ul>
<li>Currently, access to private files just depends on the <code>is_user_logged_in()</code> function.  This plugin could be developed to give more fine-grained control, such as having a folder for each user.</li>
</ul>


Private Uploads

Simple, works well, just perfect for me.
Some tips:
With the Plugin User Role Editor you can add a role like view_private_file and choose which user roles can access it. You can also redirect to a access denied page. Just modify in the Plugin file the function send_private_file like this:

    // Only return files to logged-in users
    if (!is_user_logged_in() || !current_user_can('view_private_file')) {
        header("Location: https://www.yoursite.com/access-denied");
        die();
    }


Perfect

Protects sensitive uploaded files so that only logged-in users can access them. The plugin depends on corresponding web server (e.g.
