# Previewing file output

{% hint style="info" %}
**Required guided redaction permission:** Preview project files
{% endhint %}

**Preview** mode displays the redacted content as it appears in the downloaded file.

To change to **Preview** mode, in the file heading, click the preview icon.

In preview mode:

* The boxes that cover the redacted content are always black.
* The reference codes display on the boxes.

Preview mode does not display redactions that do not have an assigned reference code. That content is not redacted in the output.
