If you are planning to reinstall your operating system or to use the same opera settings in other pc, you may want to backup all the bookmarks, wand data, settings and preferences. You can do so by following the below instructions carefully:
Before you start with make sure you have not kept the browser open.
1. First of all you need to backup the following important files:

These files are usually located in
C:\Documents and Settings\username\Application Data\Opera

NOTE: The file “opera6.ini”, contains your general Opera settings, such as cache and plug-in information. It is not recommended that you copy this file from a computer to another, as it contains a lot of paths that may be specific to your computer.

Sessions – saved windows> sessions\
Plug-ins (Windows version)> program\plug-ins\
Keyboard configuration> keyboard\
Mouse configuration> mouse\
Menu configuration> menu\
