Importing bookmarks from other programmes
To import bookmarks to Opera from other programs, go to File > Import and export and choose the program you want to import your bookmarks from. Now browse your way to the folder in which your bookmarks are located, and confirm to import.
Note-
You might want to create or set an active folder in your Panel (F4) which your bookmarks will be imported to.
In addition to importing bookmarks, it is possible to merge the bookmarks you already have by using an external bookmark manager.
A highly recommended bookmark managing program is "Powermarks" from Kaylon Technologies. Powermarks recognizes Opera, as well as Netscape Navigator's bookmarks and Internet Explorer's Favorites.
Exporting bookmarks
Some browsers, such as Firefox, can detect the presence of Opera on your computer. Therefore, it is often easier to just use the browser's bookmark import mechanism and import the bookmarks directly.
If you need to use your Opera bookmarks on a browser on another computer, you may want to export the bookmarks to an HTML file. Many browsers can understand bookmarks in this format, even if they don't understand Opera's internal bookmark format.
To export bookmarks from Opera, follow these steps:
1. Go to File > Import and export > Export bookmarks as HTML
2. Choose the file name, and click Save
3. Import the bookmark file according to the instructions of your other browser. On Internet Explorer, you find this under File > Export and import. In Firefox, go to Bookmarks > Organize bookmarks, and from the Bookmarks Manager choose File > Import.
