Relativity has a short message format which should be used for messages exported from Slack, Skype, Instant Bloomberg chat, or standard mobile phone SMS messages. A .rsmf file should include a .zip file attachment, that cannot be encrypted. A manifest file inside the zip file should have a JSON file at its root.
