Where are the sessions stored in the new opera?

Question

Browsers

Put in Mega, synchronize the Opera folder (C:\Users\Kane\AppData\Roaming\Opera Software\Opera Stable).
Recently, by accident, I cleaned my computer through ccleanner and forgot to uncheck the sessions.
In opera, I had several windows open with a bunch of tabs.
I climbed into Mega, into the basket, found the previous date. But there all the files are in a crowd, without directories.
I replace the files:
Last Session, History, Bookmarks, Bookmarks.bak
But there is no sense, as there was one window - it remains.
I noticed that the Last Session file, after being replaced, becomes 10mb in size, but after starting it loses weight to 1mb.
In a word, it was easier in the old opera. You change the extension of session.dbak to .db and enjoy life. And then the devil will break his leg (

So. Sobsna found a solution.
The Chrome Opera session is located in the file Current session.
I copied the Current session to the opera folder, it weighed 10 meters, and after a second, it became 1.5 mb.
And then it did:
I forgot to turn off synchronization in MEGA and it replaced the Current session file with a newer one.
