Could you find a way to recover the file? I'am facing the same problem, haven't saved either and there is no folder (that I know of) to recover an autosave or backup. Please help, been working on a project for very long before my laptop crashed.
Enable autobackup in your C2 right now (for next projects).
And no, there is no quick way. There are softwares that scans your disk drive to recover files but it's not easy and when you want to recover something you have to stop using the laptop because any action writes on your disk, so you are risking to re-write the sector where your file was.
