Also, try do to a search with a program called Recuva. It could search in hidden directories and sometimes may find files that were deleted even from the Recycle bin of Windows. I just did a search with it and even though my Recycle bin is empty, Recuva found 202 deleted files, with the older one being “deleted permanently” since 2019 (but is still recoverable). 
I don’t know if I’m looking at the right place, but I think there is no such block. Anyway, please don’t bother solving my problem any more. I started doing my model over again. 
I’ll take a look here too. I hope I can find it. Thank you so much
