Carbide Create Build 726....can't find NC file

Recently upgraded CC to 726. Like the improvements etc. Created a new project …was able to save project as a “Program Carbide Create V7” file but am unable to find the corresponding NC file that is to be used on my Shapeoko. Previously it was created when project file was saved. Did a search of my directories…no luck finding NC file. Anyone else have similar problem…appreciate any direction for this old retired fart…
