Since Tails 5.8 (December 2022), your data corresponding to each feature of the Persistent Storage is stored to the USB stick immediately. You don't have to restart Tails anymore after enabling a new feature.
For example, when you enable the Tor Browser Bookmarksfeature of the Persistent Storage, your current bookmarks are saved in the Persistent Storage immediately.
When the Persistent Folder feature is turned on, you can save your personal files and working documents in the <span class="filename">Persistent</span> folder.
*Tor Browser* can only access the *Tor Browser* subfolder in the *Persistent* folder. You can only save your downloads to the *Persistent/Tor Browser* folder. To upload a file, you must copy it to the *Persistent/Tor Browser* folder first.
When the Welcome Screenfeature is turned on, the settings from the [[Welcome Screen|doc/first_steps/welcome_screen]] are saved in the Persistent Storage: language, keyboard, and additional settings.
