MBL file to big for file system now lost folder ! help please

I have read the guide about SSH and Putty, I have followed the guide and enabled SSH, downloaded Putty and configured it correctly so now I have acces to the NAS this way also (see [GUIDE] Fix Dashboard Errors 3xxxx

Not sure if its any help as I don’t exactly understand what I am doing, but is it worth trying /usr/local/sbin/factoryRestore.sh noreformat am I right in thinking this wil restore the drive without losing my files?

But before risking doing that now I have access to the drive using SSH is there a way to find out what is on the drive and be able to copy files back to my WIndows 10 laptop before trying the reset? Looked around and can’t find anything that I can understand as it seems quite an advanced thing to do.

Still unabe to contact WD, really hoping for some advice.

Thanks.
