# Session Volatility

**Session Volatility** refers to the temporary nature of data within a [[bigbluebutton]] meeting. 

In the context of the Universität Greifswald's implementation:
- **Temporary State**: A BBB meeting is treated as a discrete session. Once a session is ended, all session-specific information is removed.
- **Data Loss**: Any files or presentations uploaded during the session that were not designated as "standard presentations" in the Moodle activity settings are deleted when the session ends.
- **Reset**: Restarting a BBB meeting initiates a new session based on the original Moodle activity settings, effectively wiping any ad-hoc changes made during the previous session.
