To convert NDD GPS logs to another format, you need NDrive or other Data software.

Convert a file to NDD

To convert other file formats to the "Navigation Log / ROM Dump" file type, you need software like NDrive or a similar tool.


About NDD files

The .NDD file extension primarily represents three distinct, specialized file types: NDrive Navigation data log files, NeuroLucida data files, and Nintendo 64DD disk images.

NDrive software uses .NDD files to store GPS routes, trackpoints, and navigation history. These logs are locked into a proprietary ecosystem that is largely obsolete, making data extraction highly frustrating. Alternatively, in the medical and biological fields, MBF Bioscience uses .NDD for NeuroLucida, storing complex 3D neuron reconstruction mapping. Finally, the retro-gaming community uses .NDD for raw disk dumps of the Japan-only Nintendo 64 Disk Drive magnetic disks, which are played via emulators like Project64.

Users face severe limitations when attempting to open or convert .NDD files. NDrive logs cannot simply be imported into Google Maps or standard GIS software, as they lack the universal structure of standard GPX or KML formats. N64DD disk images require specific hardware BIOS dumps and precise emulator configurations to function, and converting them to other ROM formats usually breaks the game data. NeuroLucida files require expensive, specialized academic software to read.

Because these are closed, proprietary formats, standard online converters fail to process them. Often, only the original software can properly read, export, or convert the data. However, you can bypass these limitations by using convert.guru. Just drag and drop your file to identify the format, view its internal structure, and convert it if our analysis detects a supported underlying format like raw XML or text logs embedded within the binary.

Convert.Guru analyzes your NDD file, detects the exact format, and lets you read the text inside.

Users also converted INDD, NWB, NLV and NIA files.

The NDD Converter Story

The history of Convert.Guru began over 25 years ago in California with Tom Simondi’s file-format database. A former contributor to Space Shuttle development and a software pioneer of the 1980s, Simondi established a trusted resource for file type analysis that was even referenced by Microsoft Windows XP. Today, we use modern technology to process and convert thousands of file formats while continually improving our NDD converter.
