largest NC file

What was the size of your largest NC file?
A few days ago, I made a mistake by putting a "-" in front of a value that was supposed to be positive in FreeCAD's CAM workbench, which resulted in an NC file that was 20,590 kB or 688,627 lines long.
The file was never run, since I caught the error.
So I was wondering—how large have the NC files you've generated been?
