A session file contains the state of the visualization within a context file using the .flpset extension.
The following menus are available to you for reading and writing session files:
File → Read → Session File...
File → Write → Session File...
Session files use the .flpset extension.
Note: When exiting a session without saving the session state, a dialog will appear prompting you to save the session. The same dialog will open when opening a new session file without saving the current one.
