Options > File > Save

Create backup copy — Select this option to save a number of previous versions of your part as you work. Enter the Number of copies to keep and set the Backup location. When you save a file, the previous version(s) are saved to disk using the name, but prefixed with Backup of. The latest version of the file is always saved using the name of your FeatureCAM part.

Save preview picture in file — Select this option to store an image of the part in the file. This image is displayed in the Open dialog.

Allow me to save part file after crash — Select this option to enable you to save the part file after a crash.

Save computed toolpath — For certain parts, generating toolpaths can be time-consuming and you may want to save them for the next time you open a part. The setting of Save computed toolpath controls the default behavior for saving toolpaths. Select from Always save, Never save, or Ask me to be prompted each time you save a part. The toolpath is saved as an .fmp file.

Note: This is different than saving the NC text file that the NC machine reads. Instead you are saving the FeatureCAM internal toolpath representation. If you upgrade to a newer version of FeatureCAM, the toolpath is disregarded and recomputed.
