Protects uploaded files so they can only be viewed by logged-in users
This plugin does not work with the media library. It only protects files uploaded through the plugin itself.
Requires a web server that supports .htaccess files for access control, such as Apache on Linux. Please note that even Apache on Linux 
disables .htaccess files in newer versions in some configurations, so please check to make sure your files aren’t publicly accessible. 
You can test that your files are protected by using the wp-content/uploads/ path or 
 by using the “Test link security” link on the “List all protected uploads” page. You should receive a 403 Forbidden error 
 if it’s working correctly.
This plugin does not collect any private data itself though it’s possible logged-in users may upload private data to your website using this plugin.
PRO SUPPORT 
While we attempt to provide basic support for this plugin here on the WordPress.org forums, for advanced or priority support please use the pro version. 
The <a href="https://www.mcmwebsite.com/mcm-protected-file-view-pro/" rel="nofollow ugc">pro version</a> also adds per user role file permissions, so, for instance, you can have a file that’s only accessible to a premium role, while not accessible to a basic role.

By default, <a href="https://wordpress.org/plugins/contact-form-7/" rel="ugc">Contact Form 7</a> dose not keep data it sends trough it’s contact forms. 
While plugins like <a href="https://wordpress.org/plugins/flamingo/" rel="ugc">Flamingo</a> save that data, uploaded files are not added to Media Library. 
This plugin will save uploaded files to Media Library before email is sent by CF7. 
This plugin will raise an event with the the full file path & name. 
Subscribe to <code>nmr_create_attachment_file_name</code> filter to get and/or update data before attachment is added to media library.
<pre><code>// The filter callback function.
function example_callback( $file_name ) {
 // (maybe) modify $file_name.
 return $file_name;
}
add_filter( 'nmr_create_attachment_file_name', 'example_callback', 10, 1 );
</code></pre>
Subscribe to <code>nmr_before_insert_attachment</code> filter to be able to change attachment attributes: caption and description are ‘post_excerpt’ and ‘post_content’. 
For other attributes, check documentation for <a href="https://developer.wordpress.org/reference/functions/wp_insert_attachment/" rel="nofollow ugc">wp_insert_attachment</a>.
<pre><code>// The filter callback function.
function before_insert_attachment_callback( $attachment ) {
 // (maybe) modify $attachment array.
 return $attachment;
}
add_filter( 'nmr_before_insert_attachment', 'before_insert_attachment_callback', 10, 1 );
</code></pre>
Optionally, subscribe to <code>nmr_should_skip_save_attachment_to_media_library</code> filter to be able to skip saving the attachment to media library: return true to skip, false is the default behaviour that saves the attachment to media library. Filter <code>nmr_before_insert_attachment</code> will not be called if skip was true.
<pre><code>// The filter callback function.
function skip_media_library_callback( $skip_save_to_media_library ) {
 // return true to skip saving to Media Library, false to save.
 return true;
}
add_filter( 'nmr_should_skip_save_attachment_to_media_library', 'skip_media_library_callback', 10, 1 );
</code></pre>
This plugin will send the final attachment id if you are interested in getting other details, like attachment url. 
Listen to <code>nmr_create_attachment_id_generated</code> action.
<pre><code>// The action callback function.
function example_callback_id_generated( $attachment_id ) {
 // (maybe) do something with the args.
 $url = wp_get_attachment_url( $attachment_id );
}
add_action( 'nmr_create_attachment_id_generated', 'example_callback_id_generated', 10, 1 );
</code></pre>
