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.
<h1 id="create">Creating the Persistent Storage</h1>
<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>
<h1 id="configure">Configuring the Persistent Storage</h1>
<p><strong>Restart Tails to apply the changes</strong> after selecting or
deselecting one or several features.</p>
<p>If you turn off a feature, it will be
unavailable after restarting Tails but the
corresponding files
are still saved in the Persistent Storage.</p>

When the Welcome Screen feature is turned on, the settings from the Welcome Screen are saved in the Persistent Storage: language, keyboard, and additional settings.
When the Tor Bridge feature is turned on, the last [[Tor bridge|doc/anonymous_internet/tor]] that you used to connect to Tor successfully is saved in the Persistent Storage.
When the Browser Bookmarks feature is turned on, changes to the bookmarks in [[*Tor Browser*|doc/anonymous_internet/Tor_Browser]] are saved in the Persistent Storage. This does not apply to the [[*Unsafe Browser*|doc/anonymous_internet/unsafe_browser]].
When the Thunderbird feature is turned on, the email, feeds, and OpenPGP keys in the [[*Thunderbird* email client|doc/anonymous_internet/thunderbird]] are saved in the Persistent Storage.
<p>Since Tails 4.13 (November 2020), <em>Thunderbird</em> uses its own OpenPGP keyring,
different from the keyring used by <em>GnuPG</em> and <em>Kleopatra</em>. You don't need to enable the GnuPG
feature anymore if you only use OpenPGP encryption in
<em>Thunderbird</em>.</p>
When the Pidgin feature is turned on, all the configuration files of the [[*Pidgin* internet messenger|doc/anonymous_internet/pidgin]] are saved in the Persistent Storage:
The configuration of your accounts, buddies and chats.
Your OTR encryption keys and keyring.
When the SSH Client feature is turned on, all the files related to the secure-shell (SSH) client are saved in the Persistent Storage:
<p>If you manually edit the <i>~/.ssh/config</i>
configuration file, make sure not to overwrite the
default configuration from the
<i>/etc/ssh/ssh_config</i> file. Otherwise, you might weaken the
encryption defaults or render SSH unusable.</p>
All the files in the */live/persistence/TailsData_unlocked/dotfiles* folder are linked in the *Home* folder using Linux symbolic links.
All the files in subfolders of */live/persistence/TailsData_unlocked/dotfiles* are also linked in the corresponding subfolder of the *Home* folder using Linux symbolic links.
