My CAM software writes programs with an extension .NC at the end of the program number ( O1234.NC), My CNC machines will not recognize this when I am trying to upload it to the machine from a USB. I have been renaming the file with no extension and it works great. But now that I am using Windows10 I am having trouble renaming a file with no extension. Is there a way to get the machine to recognize the file with a .NC extension?? to avoid renaming all together
