is there a way for me to recover my accidental overwritten .fla project?

I was working on my character for my new channel and didn't name it giving it the name "untitled-1.fla" and saving it on my computer. I wanted to make a quick test animation, and accidentally saved it as "untitled-1", overwriting my character. I've tried looking through my tmp folder. I tried looking for the "RECOVER_" file. I tried looking at "window > history". nothing. this fr discouraged me. after all that work, how could I make such a simple but stupid mistake?
