<h1>Retention of files<a class="headerlink" href="#retention-of-files" title="Permalink to this headline">¶</a></h1>
<p>Nextcloud’s Files Retention app allows to automatically delete files that
are tagged with a collaborative tag and have a certain age.</p>
<div class="section" id="example">
<h2>Example<a class="headerlink" href="#example" title="Permalink to this headline">¶</a></h2>
<p>After installing the Retention app as described in
<a class="reference internal" href="../installation/apps_management_installation.html"><em>Installing and managing apps</em></a>
navigate to the configuration and locate the Workflow settings.</p>
<blockquote>
<div><div class="figure">
<img alt="Sample rule to delete files after 14 days." src="../_images/retention_sample.png" />
</div>
</div></blockquote>
<p>The rule from the example will delete all files tagged with <code class="docutils literal"><span class="pre">Temporary</span> <span class="pre">file</span></code> after 14 days.</p>
</div>
<div class="section" id="common-misconfigurations">
<h2>Common misconfigurations<a class="headerlink" href="#common-misconfigurations" title="Permalink to this headline">¶</a></h2>
<div class="section" id="public-collaborative-tag">
<h3>Public collaborative tag<a class="headerlink" href="#public-collaborative-tag" title="Permalink to this headline">¶</a></h3>
<p>Similar to <a class="reference internal" href="access_control.html"><em>Files access control</em></a> retention should use <code class="docutils literal"><span class="pre">restricted</span></code> or <code class="docutils literal"><span class="pre">invisible</span></code>
tags. Otherwise any user can remove the tag and the file is not removed after the given
period. Use <a class="reference internal" href="automated_tagging.html"><em>Automated tagging of files</em></a> to assign such tags to newly uploaded files.</p>
</div>
<div class="section" id="file-age">
<h3>File age<a class="headerlink" href="#file-age" title="Permalink to this headline">¶</a></h3>
<p>Currently retention is based on the creation date of the file. The sync client sends
the <strong>original</strong> creation date to the server, while uploading through the web interface
will create a new file with a <strong>new</strong> creation date.
We hope to be able to add a <code class="docutils literal"><span class="pre">upload</span> <span class="pre">date</span></code> to the filesystem soon, which would make more
sense. Until then this potentially unexpected behavior has to be taken into account.</p>
