What is a GC file?

GC files mostly belong to LightBurn. GC files are not a single format but represent different types of data depending on the software and use.

G-code instructions: These files contain commands that control machine tools like laser cutters and CNC milling machines. For example, applications such as LightBurn and Autodesk’s ArtCAM use them to direct cutting and milling paths.

Greeting Card Studio files: In some cases, a GC file holds project details for greeting card design used by software such as Greetings Card Factory or PrintMaster. They store layout and design information that is later printed.

Genericode code lists: Some GC files are XML based and follow the Genericode standard. They contain standardized code lists used for data exchange as explained in the Genericode documentation.

NOAA satellite data: A few GC files are used to store Level 1b data from NOAA satellites. These files hold meteorological data that specialized NOAA software can process, as seen on the NOAA website.

FilExt.com note: Depending on which GC file you have, you might open it with a text/XML editor to inspect the content or with the specific application that created it. In many cases the file is plain text (especially for G-code or Genericode), but editing should be done with care because even small changes can affect machine performance or data accuracy.

How to open GC files

You need a suitable software like LightBurn to open a GC 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 GC file correctly, try to right-click or long-press the file. Then click "Open with" and choose an application. You can also display a GC file directly in the browser:. Just drag the file onto this browser window and drop it.

How to solve problems with GC files

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