@hantuuu said in How do I restore old opera bookmarks?:
now what to do? copy those bookmark to my original opera installation folder?
Yes. That's one way. The other way would be to goto the URL opera://bookmarks in the standalone installation, click the drop-down at the bottom left and export the bookmarks to an HTML file. Then in your normal Opera, goto the URL opera://settings/importData, choose "Bookmarks HTML file" in the drop-down and import the HTML file. Then, goto the URL opera://bookmarks and move them where you want.
That 2nd method would be better if you have existing bookmarks in your regular Opera that you want to keep.
