The File menu

This menu handles the current session. By default the following menu items will be present:

New Session

This creates a new session.
If you have not saved your current session then a warning will be displayed.
Starting a new session without saving the current session will loose all of the data in the current session.

Open Session...

This opens a session that has been previously saved.
Opening a session without saving the current session will loose all of the data in the current session.

Save As...

This saves the current session.
Once a session has been saved you do not need to save it again - any changes will automatically be saved.
If you want to keep a snapshot of the session then you can save the session under a different name - any changes you make after this will only be saved under the last name.

Properties...

This displays the Session Properties dialog.
This allows you to set the session name and description.

Exit

This will exit ZAP. If you have not saved the current session then you will be given the option to do so.

Note that plugins can add additional menu items.
