If you start Tails from a USB stick, you can create an encrypted Persistent Storage in the free space left on the USB stick.The files and settings stored in the Persistent Storage are saved encrypted and remain available across different working sessions.
<p>If you receive the error message while running Tails using <i>virt-manager</i>, then you need to [[run Tails from our USB image|doc/advanced_topics/virtualization/virt-manager#usb_image]] instead of our ISO image.</p>
<p>The error message <em>Error, Persistence volume is not unlocked.</em> means that the Persistent Storage was not unlocked in the Welcome Screen. You cannot use or configure your Persistent Storage but you can delete it and create a new one.</p>
<p>To change the configuration of your Persistent Storage, restart Tails, unlock the Persistent Storage, and choose <strong>Applications</strong> ▸ <strong>Tails</strong> ▸ <strong>Configure persistent volume</strong> again.</p>
