Attempting to exit Opera only closed a second 14-tab window. These could not be recovered.
Is it possible to connect the current session with the first window and the tabs that have been changed in the meantime to an older saved session file? Or open an older session in opera?

Thanks
I closed opera and renamed the next-to-last file in the newest file.
But after restarting opera there wasn't any tab.

With the Last Session-file in older versions, it was possible to start with older tabs by changing the file name.

So, I want to know, how is it possible to start opera with an older session.

Where will Sessions be saved in the younger versions?
It's not the folder C:\Users\XXXXXXX\AppData\Roaming\Opera Software\Opera Stable anymore and the file "Last Session".

Is it any file in the folder C:\Users\XXXXXXX\AppData\Roaming\Opera Software\Opera Stable\Sessions?
How can I import this file?

How to restore the last session after Opera crashed?

It was'nt successfully, deleting the latest Session_xxxxxxxxx-file and renaming the last one before Opera crashed.
It was much better, as sessions were saved in "Last Session"-File.

Wo werden Sessions in den jüngsten Versionen gespeichert?
Es ist nicht mehr im Ordner C:\Users\XXXXXXX\AppData\Roaming\Opera Software\Opera Stable die Datei "Last Session".

Ist die Datei im Ordner C:\Users\XXXXXXX\AppData\Roaming\Opera Software\Opera Stable\Sessions?
Wie kann man diese Dateien "importieren"?
