How is a Relativity Short Message Format RSMF file created?

The correct answer is C. Files must be generated using the RSMF specifications before they are imported into Relativity. Relativity’s official Short Message Format documentation explains that to use the Short Message Viewer, you first need to create an RSMF file, and the example/specification pages describe the required structure and header information that must be present before ingestion using Processing. Relativity also states that Processing is the recommended method of importing RSMF files into Relativity, which means the RSMF file already exists when Processing begins.

This rules out the other options. Relativity does not say that it automatically creates RSMF on-the-fly for all non-document data. It also does not describe a processing-profile feature that converts arbitrary XML from chat platforms into RSMF during import. Nor is there a document-list mass operation that converts conversations into RSMF. Instead, RSMF is a defined external format that must be constructed according to Relativity’s published specifications, then imported and processed to preserve message metadata, attachments, and near-native review behavior. Therefore, the correct answer is C.
