How do I recover unsaved scans when Auto save option is enabled

How do I recover unsaved scans when  Auto save option is enabled?

I use Acrobat X and find the Auto Save under /Edit/Preferences/Documents in the Save Settings section.  "Automatically save document changes to temporary file every:" IS selected, and a duration of 5 minutes is specified. There isn't a path specified where the temporary document is stored, nor specification as to the file naming or format.

I found these posts

Is it possible to recover unsaved scanned documents after a crash?

and

Re: Autosave: How to recover a lost document?

Which at best indicate I might find a file in a Temp folder, such as

\user\Local Settings\Temp - possibly called A9R1F2.tmp

C:\Users\AppData\Local\Temp

or in my case using Win 10

C:\Users\Peter\AppData\Local\Temp - would the file be wct4B8F.tmp ? It's the only file which could possibly be large enough to have my scans.

From time to time I need to sleep or hibernate my laptop before my scanning is complete (I tend to scan unrelated documents in a batch, then later extract each document from the scan and save to disk). USUALLY this present no issues.

HOWEVER, from time to time an external event occurs, such as my laptop loses power (my bad) but more often MICROSOFT forces an update and reboot while my laptop is on OR EVEN after I put my laptop to sleep and then later turn it back on. WHEN THIS HAPPENS, I lose my in process scanned file even though the Autosave should have retained the data...

I very much would like to recover my unsaved scans, especially since the program is supposed to allow me to do so. But Acrobat Pro will not allow me to open the tmp files - it states the files are not in the acceptable format.
