Error while saving the file

I think i have lost all day of my work!!!!!!!!!!!!!!

I was working on animation. And i saved the file. I know that in that moment all of automatic saving was destroy by the animate. ( WHY ADOBE, WHY!?)

And know happy to restart the computer (coz of lack space on my SSD) I think. Computer said that was lack of memory i dont know if that was accualy a RAM or a Drive

But i had to.

So i saved the file! NOTHING WRONG! AND RESTART THE COMPUTER!

NOW I TRY TO OPEN THE FILE!!!!!! AND A ERROR OCCUR!!!! WHY THE FREAK?

WINDOWS 10

error message is "Error while opening the file"

WHAT HAPPEND IS THERE A POSSIBILITY TO OPEN IT? OR REPAIR IT?
