Lost all the lines of code inside a .php of a session

Hello,
My .php file still exists but has nothings inside. I did some changes before and tried to save it but when i try to open it again everything was erased. Is there any way to find a previous session so i can restore it? My temp sessions are saved in the temp of winscp

Did you try to locate the temporary copy of the file in your local temporary folder?

Can you reproduce the problem?
