Hi,
As it wasn't a CS6 crash so it won't start up with the recovered file, if you had been working on it for longer than your Auto-Recover interval was set it may be present in "C:\Users\<user name>\AppData\Roaming\Adobe\Adobe Photoshop CS6\AutoRecover" note that is only windows for mac someone else may wish to step in.
