Assets Manager is a self-hosted file sharing tool. Born out of the need for a file sharing tool that was not blocked by high security firewalls, such as many existing file sharing services are, Assets Manager was developed. When you upload a file, or set of files, Assets Manager generates obscured links to the files so that you can control how those files are shared.
<a href="http://www.jackreichert.com/2015/11/15/how-assets-manager-replaced-our-sharefile/" rel="nofollow ugc">Here’s how it works.</a>
<h4>Features</h4>
<ul>
<li>Set an expiration period for when the file link will expire.</li>
<li>Disable links after they’ve been shared (no more fretting when sending out emails).</li>
<li>Force anyone trying to access a link to log into your site.</li>
<li>Creates landing page for each asset post type collecting files uploaded together into one link.</li>
</ul>

Special thanks to @binmind for his extensive QA testing of the company’s plugin, his testing was crucial for development of the proof of concept and making sure everything was working as it should.

Easy Symlinks lets you create and manage symbolic links (symlinks) directly from the WordPress admin dashboard — no command line required.
Features:
<ul>
<li>Create symlinks by specifying a target directory and link path</li>
<li>Delete symlinks individually through a simple dropdown interface</li>
<li>Automatic environment detection for Pantheon hosting (Dev, Test, Live, Multidev)</li>
<li>Filesystem writability checks — prevents symlink creation in read-only environments</li>
<li>Displays existing symlinks and their targets</li>
<li>Tracks only symlinks created through the plugin</li>
<li>Duplicate symlink detection — prevents creating symlinks that already exist</li>
<li>Preset symlinks — auto-detects plugins like Wordfence and offers one-click symlink setup</li>
<li>Optional database cleanup on plugin uninstall via Settings tab</li>
</ul>
How to use:
Navigate to Settings > Easy Symlinks in your WordPress admin dashboard. The “Presets” tab auto-detects installed plugins that need symlinks (e.g., Wordfence on Pantheon). Use the “Add Symlinks” tab to create custom symlinks, the “Delete Symlinks” tab to remove them, and the “Settings” tab to configure plugin options.
For common symlink configurations on Pantheon, refer to the <a href="https://wordpress.org/support/topic/list-of-common-symlinks-in-pantheon" rel="ugc">list of common symlinks</a>.
Important notes:
<ul>
<li>This plugin only tracks symlinks created within the application. Symlinks created from the filesystem or command line are not tracked.</li>
<li>Best used in Pantheon Dev or Multidev environments in SFTP mode.</li>
<li>Symlink creation is disabled in read-only environments (e.g., Pantheon Test and Live).</li>
</ul>

Easy Symlinks

This plugin is very useful on secured host that only allows writable permission on a particular folder

Very Useful

Manage symbolic links from the WordPress admin. Create and delete symlinks without CLI access, ideal for Pantheon environments.
