Filr – Secure document library


Filr – the secure document library

Create and manage secure document and file libraries has never been easier.

Filr creates protected areas on your file system and let you easily upload, manage and display documents files on your website.

You can decide if you want to share a unique direct download link to a document library or display a complete library of docs and files on your website.


Filr includes a shortcode to output a document and file library with a search, filters and a pagination.

Use the shortcode: [filr library="library-a"] and show a list of your documents and files.


Easily display the name, the latest modification date, file type and download link in your library.


Check the security status within the settings and choose between different settings.

Filr includes a small status tool to show you if your server is missing any requirements for Filr to work.


Reorder the columns, modify colors, texts and include or exclude specific rows from your library shortcode.

You can also set an alternative text for empty libraries to give your users further explanations.

Auto cleaner

To prevent your filesystem for any clutter, Filr has a built-in file cleaner.

It takes care that no unecessary files are left on your filesystem.
You never need to open your FTP tool again.

How to use

After installation and activation go to Filr -> Settings and configure your uploads folder and check the server settings.

When you are done, create your first file with “New File”, give it a title, upload your file and after saving it you can copy the download link.

Otherwise assign it to a library and copy the shortcode to display it on your website.


The free support is exclusively limited to the support forum.


Filr is coded with modern PHP and WordPress standards in mind. It’s fully OOP coded. It’s highly extendable for developers through several actions and filter hooks.

Filr has your website performance in mind – every script and style is minified and loaded conditionally.


Filr is completely translatable with WPML and Polylang.
Simply use the language switcher and translate all settings.

This plugin does what it was made for in a very simple, intuitive and resource-saving way. Although the support from the author is worth mentioning, because he answered very quickly (less than 24 hours). Thanks for this plugin!

If you need an upload-protection use Filr! It is a simple plugin but fits all needs of file-/directory-protection. The free version is quite powerful, pro version has a solution for all cases of protection. Thanks for creating this!

Filr is a simple, intuitive and powerful file viewer plugin. After using it with more than 10 libraries including 500+ files it is working without any problem. Adding, protecting and sharing of files/documents was never easier for me. The support is also very fast and polite … thank you for this plugin!
