My computer cut out whilst I was working on a .py file in Idle. I had saved it numerous times, but when I turned my computer back on the file was completely blank. Despite being completely empty in Idle, the file registers as 40KK, which couldn't be possible if there was nothing in it. I'm on Windows 10, and have tried "restore previous options"; nothing came up. I have no file history or backup drive setup. Is the file recoverable, and if so, how?
