@leocg What is the backup of your old Opera profile directory?
Which of these folders am I going to copy and paste?

Yes, I started with the same account, and I also enabled synchronization and it doesn't work.

@leocg Hello, the synchronization did not work..
And how do you paste the contents of the profile directory into the same directory in the new installation?
Is there a video where you can see how to do that?

Hello, what are the steps to transfer the opera file to another PC?
