Is there a way to recover recovery files?

Hi guys.

I searched on the forum but couldn't find what I need, so here's the thing: my powerpoint crashed while I was working, and when it opened back, I accidentally closed the recovery file without saving it. Now I lost my work. Is there a way to recover, even after closing it?

It's not on that AutoRecovery Files Office 2011 hidden folder, there's just an empty temp file.

Thanks for your help.
