We are introducing a new file extension for Copilot pages, ".page". This new file extension will continue to support admin toggles, sensitivity labels, data loss prevention, multi-geo, Purview eDiscovery, version history, export, audit logs, and data subject requests. The functionality and support for the .page file extension will be identical to the existing .loop file extension, with the only difference being the file extension and the associated file icon.
