<p>We are often asked to implement new features of the Persistent Storage: Tor Browser preferences, Tor configuration, desktop background, mouse and touchpad settings, and so on. See the [[!tails_gitlab groups/tails/-/issues?scope=all&utf8=✓&state=opened&label_name%5B%5D=C%3APersistence desc="list of issues about the Persistent Storage in our GitLab"]].<p>
When the Additional Software feature is turned on, a list of [[additional software|additional_software]] of your choice is automatically installed every time you start Tails.
The corresponding software packages are stored in the Persistent Storage. They are automatically upgraded for security after a network connection is established.
<p>The packages included in Tails are carefully tested for security. Installing additional packages might break the security built into Tails, so [[be careful with what you install|additional_software#warning]].</p>
<p>The Dotfiles feature only links specific files, and not entire folders, from the Persistent Storage. Accordingly, empty folders are ignored, as shown in the above example.</p>
