My computer has a problem and it automatically shutdown, therefore I lost all the history opened files.
I found a lot of links in SumatraPDF-settings file, but I do not know how to configure it to make it open again.
Could you please suggest a solution to my problem.
This is related to the fact that SumatraPDF will only save the session at time of a clean EXIT
So if you crash the list is empty, Once you are happy with a session you need to manually Exit and save (backup) the settings file so you can replace it after either a crash or unintended reboot
review that thread and see if it helps
