Backup file created by NeatReceipts, a tool in NeatWorks, which is an older version of the digital filing system software, Neat 5; contains a backup of your scanned documents, including receipts and business cards; similar to the .NBAK and .NWBAK files.

To create a NRBAK file, select Tools → Database → Backup, use the default save name, choose a save location, and click Save. To restore a database in versions before Neat 5 using the NRBAK file, select Tools → Database → Restore, select "Browse," navigate to your file, select "Open," and then click Restore. In order to restore an old database such as the NRBAK file, you will need to run the "Neat Data Migration Utility," select "Browse," choose your backup file, provide a cabinet and database location, and click Migrate. NOTE: The NRBAK file extension was used up until version 4.6 of NeatWorks. It was then replaced by the NWBAK extension. The NWBAK extension was used up until version 4.9 when it was then replaced by the NBAK extension with the release of Neat 5.
