.NC File Extension
File Type 1Mastercam Numerical Control File
What is an NC file?
An NC file is a data file created by CNC Mastercam, a suite of CAD tools used for designing and manufacturing mechanical components. It contains numerical control instructions for directing a CNC machine tool, such as a drill or boring tool, during the production of the component.
You most likely will only encounter a Mastercam NC file if you are an engineer or machinist that designs and produces mechanical components with Mastercam software. NC files are created when a user saves a 2D or 3D machine toolpath in Mastercam. Users typically save their NC file(s) to a portable storage device, such as a USB flash drive, then transfer it to a CNC machine tool to cut the toolpath from a piece of material, such as wood, plastic, or metal.
File Type 2mcrypt Encrypted File
.NC File Association 2
An NC file is a file encrypted with mcrypt, a Linux crypting utility that allows users to encrypt and decrypt files or data streams. It contains a file encrypted with an algorithm, such as md5, tiger, or whirlpool, specified by the user and secured with a passphrase.
mcrypt is a tool that replaces the crypt() package and crypt(1) command. The program provides the option to encrypt and compress a file with GNU zip (gzip) compression, which appends the ".gz.nc" extension to the file, or encrypt and compress a directory as a TAR archive compressed with gzip, which appends the ".tar.gz.nc" extension to the file.
File Type 3NetCDF File
.NC File Association 3
Data file created in the netCDF (network Common Data Form) format, a format used for storing multidimensional data in a manner independent of the platforms and disciplines for which it is used; often used by scientific researchers for GIS, atmospheric, climate, and ocean model data, as well as for data in other related fields; includes descriptive information about the data in addition to the data itself; used for storing and interchanging data.
NC files can be manipulated using Unidata's free netCDF tools, a set of libraries that provide interfaces in the Java, C, C++, Fortran, and Perl programming languages. The netCDF tools maintain backward compatibility with any previous file format versions. NC files are also supported by many other applications and command line utilities.
The netCDF format is recognized by organizations such as NASA's Earth Science Data Standards group, the Open Geospatial Consortium, and the Federal Geographic Data Committee.
