@leocg where do I find the profile directory?

Hi,
I have copied the AppData folder from my old laptop to my new computer (in a new folder separate from AppData on my new computer) and I would like to try and establish the same Opera set-up in terms of the current session, the bookmarks and, importantly, the workspaces. I have already identified some of the relevant files in AppData\Roaming\Opera Software\Opera Stable\Default, I just want to make sure I don't miss and/or break anything. So, if I understand this correctly, I need to copy Bookmarks, Bookmarks.bak, BookmarksExtra and the Sessions folder to the same folder on my new computer, correct? Is there another folder or file I need to copy to take into account the structure of my tab islands and workspaces? What happens if I just copy the mentioned files and folders as is, does that break anything?
