What is a NDR file?
A .NDR file can belong to several different software applications. The most common use is a compiled report document created by Rave Reports or Embarcadero development tools. Other software, like ComponentAce ReportPrinter, also uses the .NDR extension for saved report files.
Additionally, the .NDR extension is used for specialized technical data. This includes noise dosimeter data files from Svantek, CAD/CAM manufacturing data from C&G Systems, and engraving machine design files for Gravograph hardware. Finally, it is also known as a Nintendo 64DD Emulator ROM Save File used by the Project64 gaming emulator.
How to open NDR files?
Because .NDR has multiple possible meanings, you must know the file origin to open it correctly. You can use Rave Reports for business reports, or Project64 if you are handling a Nintendo 64DD save file.
