thanks for your comments soulviolence. I do have the AppData folder backed up, and there is a Roaming folder inside the same, but it has no folder by name Opera. I could see only a Microsoft and Windows folder in there. I am sure that I had backed up everything. Should I be looking elsewhere for Opera related files?

Thanks for your comments. To answer the question from Michael, I did not use an option such as "easy transfer", but pretty much did dump the entire C drive to an external hard-disk. So I guess I should have all of the data that I used to have on my system before it was replaced. I was wrong about the assessment that I had downloaded Opera 12.17 and upon installation, it was automatically updated to the latest version. I had installed a later version by mistake. But this time, I did download Opera 12.17 from the link provided by lem729 and I could install and start the browser without any update. Now I could see the exact same directory structure inside the new Opera folder, as I had in my backup. I tried replacing the bookmarks.adr file inside the defaults folder with what I had in my backup. When I restarted the browser after this, I could not see my bookmarks. So I decided to take it to the next level. I replaced the entire contents of the Opera folder with the files/folders in my backup, but even after that, upon restarting, I could not see my bookmarks. I am sure that I am missing something. I am willing to mail the entire directory, zipped, and whatever other related files anyone might need to try this out at their end. This is the last resort I am looking at.

lem729, I did as you suggested but as soon as I installed Opera Presto 12.17, the auto-update option kicked in and updated Opera to version 21, and upon a restart of the browser, I was back at version 22 again, with the same interface and the same set of options. In essence, I am now back to square one. I could not find the files that you had mentioned under C\Users directory path, even after the re-installation. Based on this outcome, I presume I would have to give up the hope of retrieving my old bookmarks. As a user this is quite frustrating to me, and I deem it a high-handed approach on the part of Opera, to leave users with no option of backward compatibility. This in my opinion is a classic example of developers doing their own thing, without bearing in mind the preferences of the end-users as well. At this point, I am seriously considering abandoning Opera forever, for good, and choose other saner options instead.

thanks lem729 for your detailed guidance. I was not aware of the profile location under C/Users, so I did copy only the Opera folder under C:\Program Files as part of my backup. I will have to follow your procedure about uninstalling Opera 22, installing Opera 12.17 and then reinstalling Opera 22. I can see that the Import Bookmarks option is currently greyed out in my Opera 22 browser, and hopefully, as you suggest I would be able to use the feature once I have installed Opera 12.17 and retrieved all my bookmarks, and subsequently installed Opera 22 on top. I shall keep you posted. As you say, fingers crossed at this point

Thanks lem729 for your comments. The OS is Windows 7. My system was replaced as I had mentioned previously, hence it was not an upgrade but a fresh installation. I did back up all the Opera data from my previous system (I copied the entire folder C:\Program Files/Opera to an external hard disk), but as I had written in a previous post I cannot find any file by name bookmarks in the data backed up from the previous version of Opera. For that matter, I cannot see the file in any of the folders relating to Opera 22 as well. It could be that I am not right about the version of the Opera I had previously before the system swap, and I had mentioned Opera 21 based on the fact that I could see an Opera 21 installer in the downloads folder from my previous machine. So I would like to know, if I had to retrieve the data somehow from the bookmarks.adr file into Opera 22, is there a way to do this, even if I had to convert the file to a different format before doing so? Can you help me with the related steps?

that is not useful, because I know that all my opera related files are under C:\Program Files\Opera, which is the path shown in about Opera as well. So I would need more specific information, as to which file to copy to the related folder in Opera 22 so as to retrieve my bookmarks.

Thanks lem729 for your comment. I am not sure where to find the bookmarks file in the Opera 21 folder. I cannot see a file by that name, except for bookmarks.adr inside the defaults folder. Can you provide me with some pointers?

Hello,

Recently my system was replaced and in the process the older version of Opera I had on my system (Opera 21.0.1432.67) was removed and the Opera 22 was installed instead. I had made a back up of all my previous Opera files before the system swap, and it also has the bookmarks.adr file. But I cannot figure out how I could get my bookmarks from this file into the new version of Opera. Everything looks so new and complex, and there appears no straightforward way to get the bookmarks from the .adr file. Even the directory structure inside the Opera folder is nothing similar. Can anyone please guide me on this? Greatly appreciate your help and I hope there is a way to get back my bookmarks. It is quite exasperating when the browser developers make fancy changes without any indication or guidelines to the users about how to port data from previous versions.
