You can move sessions from one workspace or folder to another by clicking on the More options icon (the three vertical dots)on the session card, clicking on ‘Move to…’ and selecting the destination workspace or folder.
Moving sessions is restricted to sessions where you are the owner of the session. You must also own, or be invited to another user’s workspace in order to move a session to that workspace.
So, for instance, you may move sessions between folders in any workspace you’re the owner of, but you cannot move a session from one folder to another within your workspace unless you are the owner of that session.
