recovery after a crash

My project crashed and unfortunately, I shut it down before I read the information on saving the temporary file ("Editor Crash:Where is Scene Data..."). The temp folder is now empty but I do have data in "New Terrain.asset". Is this retrievable? How does one go about it? Thanks for any advice!

there is not any official tool to do that but you can email support and they might have a solution.

Agree with Ashkan_gc or you may use Bitwarsoft to give it a try.
