Hey.
I greet in advance for the use of the underrated Opera House
Naturally, the most effective way is to set up an account in Opera Sync and use the tabs, history, cookies, passwords, etc. in the operatic cloud.
If you have aversion to sending your stuff to the internet, it depends on what you care about, but I assume it's about:
1. Bookmarks
2. History
3. Browser settings
4. Logins and passwords
1. You export the tabs by clicking CTRL + SHIFT + B and the "Export Bookmarks" button. Alternatively, you can copy the "Bookmarks" file from this folder that you mentioned. This is the SQLite database that you can view any SQLite editor / viewer, but the manual editing of this file is not going to end well. In the same way, if Opera in some version decides to change the structure of this database, then its copy may become unreadable by a newer version
2. History can not be exported, but it is also as an SQLite file under the name "History"
3. These things are in the "Preferences" file.
4. The most important problem with the saved passwords and logins is that they are kept in the "Login Data" file (it's easy to guess another SQLite database) and the passwords are encrypted using the Windows (in your case) Crypt32.dll library. It is possible to recover them using a tool such as ChromePass from Nirsoft, but it will be possible only on the computer on which it was created, and thus, you will not be able to copy this file to another computer.
In addition, you can copy files that define your website preferences like "Top Sites" and "Visited Links".
Copying "Cookies" and "Web Data" in theory should transfer individual settings
websites but I did not pass the exam.
