<a href="https://www.pexlechris.dev/library-viewer/for-woocommerce/" rel="nofollow ugc">LIBRARY VIEWER FOR WOOCOMMERCE ADD-ON</a> has been released! Check it 😉
With Library Viewer, you can display the containing files and the containing folders of a “specific folder” of your (FTP) server to your users in the front-end.
The significant difference from other similar plugins is that: 
1. You can allow users to view that the files exist, but cannot open them if they are not logged in (or if they are not administrators, or authors etc…). 
2. You can allow users to view files in a custom viewer or redirect them through a RESTful web service of your choice(examples exists below).
<a href="https://www.pexlechris.dev/library-viewer/demo-wp" rel="nofollow ugc">DEMO</a>
For this plugin (the free version), the “specific folder” is the folder 
“library” of your httpdocs(yoursite.com/library). 
If you want to display other folder (and its files) that isn’t contained in yoursite.com/library , you need to use the path parameter of <a href="https://www.pexlechris.dev/library-viewer/pro-wp" rel="nofollow ugc">Library Viewer Pro</a>.
This plugin adds the [library-viewer] shortcode in your WordPress site! 
So the only thing that you must do to display the folders and files in the front-end is to add this shortcode in a post, page, widget etc.
The [library-viewer] shortcode get optional parameters that extend the functionality of plugin:
