Clicking this button will show the default CNC Output directory configuration in Windows' File Browser. Within this directory, you will find CNC files, which contain the raw instructions generated and output by MillBox. These files are post-processed and ready to be sent to the machine's controller for execution or milling.
When you access this directory, you'll find a list of all the CNC files you've generated, with the only exception being if the user or dealer has configured specific machines to output to a custom directory (using Ctrl+D).
