Importing opera mail
I have used Opera's built-in mail client on Windows, and when I left the company I took with me Profiles folder. In it, there is n2xdb9mv.default/Mail/ sub-folder, and within a "Local Folders" sub-folder. Every mail folder I made is there. How can I import them in Opera, or can I read them with some other mail client?
I have tried an Import feature of Opera, but it asks for opera.ini file, which I don't have.
That was the first thing I tried, but to no effect
You should have an accounts.ini file in your \profile\mail\ folder. That's what you need to import mail accounts.
Just copying the \profile\mail folder and all of its subfolders to the new installation's profile folder should work without having to import anything.
