How to recovery an backup

[Marcel Bueno de Paula]

Hello,

I have the notepad++ installed since 2015 and never had problems. Today after reboot the computer, i open the notepad++ and it not recovery the session.

I receive a message about config.xml and confirm to reload.

I look my backup folders and have all files there, but when i tryed to open it open just in hexadecimal charcteres and not the real file.

How to recovery that files?
