Hello - I'm using Acrobat Reader DC, and if my reader closes unexpectedly, I am unable to open autosaved files. When prompted to load them upon startup of the program, I get the message "There was an error opening this document. Cannot recover original file" once for each file. This has happened for every autosaved file for several months now. Any tips on how to resolve this?
I have the same problem, also for several months now. Acrobat DC, fully up to date.
It is the most irritating when one leaves one's work open overnight or over lunch, and Windows decides to restart itself while one is not looking. You return to find your document and changes gone, your hopes of recovery are raised on opening Acrobat with the "shall we recover your files" ... only to have your hopes dashed when "there was an error opening this document."
Maybe tell us where the backup is stored so we can look for it manually?
How long after Adobe closes is the backup deleted?
