What is an NCI file?

NCI files mostly belong to MasterCAM.

MasterCAM CNC Machine Code File:
This NCI file is used to store CNC machine instructions. It holds precise toolpath data and other machining commands used to drive milling, drilling, or cutting machines.

Used in CAD/CAM environments, especially with MasterCAM.
Data here controls machine operations in a manufacturing setting.

ZIP Archive for IETM:
Other NCI files are ZIP archives that act as a container for technical manual data in the IETM archive file format. They bundle together documentation and media elements for interactive electronic technical manuals.

Compressed format using ZIP technology.
Often associated with technical documentation from specialized agencies; more details can be found on the DLA webpage.

Choose the proper application: use MasterCAM or similar CAD/CAM programs for CNC code files, or standard ZIP extraction tools for the archive type.

How to open NCI files

You need a suitable software like MasterCAM to open an NCI file. Without proper software you will receive a Windows message "How do you want to open this file?" or "Windows cannot open this file" or a similar Mac/iPhone/Android alert. If you cannot open your NCI file correctly, try to right-click or long-press the file. Then click "Open with" and choose an application. You can also display a NCI file directly in the browser:. Just drag the file onto this browser window and drop it.

How to solve problems with NCI files

Associate the NCI file extension with the correct application.
Update your software that should actually open cnc machine code files. Because only the current version supports the latest NCI file format. Search, therefore, e.g. on the manufacturer website after an available MasterCAM update.
To make sure that your NCI file is not corrupted or virus-infected, get the file again and scan it with Google's virustotal.com.
