What is .NRF file extension?
Document folder file created by NeatWorks, a digital document organizing application; contains an exported copy of a Neat document folder that can be shared between Neat users; replaced by the .NDX extension when Neat 5 was released.
To create a NRF file using NeatWorks (older version of Neat 5) select Export ? Document Folder File (.ntf), choose the save location, name the file, and click Save.
To import a NRF file into Neat 5, select Import ? Neat File..., click "Browse," navigate to your NRX file, and click Open.
NOTE: The NRF file is similar to .NRT and .NRX files, which are used by older versions of Neat.
