The nrf file extension is associated with IBM Domino, the server software formerly known as Lotus Domino.
Domino uses NRF data to notify clients that a database that previously existed on the server no longer does. This avoids requiring the client to perform a full path search of the Domino server for the missing database, which is an expensive operation.
NRF files are server-side support data rather than user documents or databases. Domino was available for Microsoft Windows, and these files are intended for the software's internal use.
nrf files are used for internal purposes by IBM Domino and are not intended to be opened as ordinary documents. They should be handled by the Domino server and should not be edited manually.
An nrf file is internal Domino redirection data and has no meaningful document conversion or export path. It should be left for Domino to manage rather than converted to another format.
