Thanks again. You have tried to help. But I will have to do this exercise thousands of times.

Dear burnout426,

Thanks, but what you described is for mails stored in the current version of Opera, not for mails stored in Opera 10.63.

Dear burnout426,

Thanks for your guidance. I will try this and revert back soon.

In my Opera 10.63, I have to very frequently search for mails having my chosen keywords -, some time in the 'From' header, some other time in the 'Subject' header, and other times in some other headers.

Some time I have to search for one keyword in the 'From' header, and/ or another keyword in another header.

Can someone please guide me how to accomplish this?

I have over 450,000 mails in my Opera 10.63 which I am now using for my work.

There are many many mails which are duplicate/ triplicate/ quadruplicate/ etc.

Can someone please guide me on how to remove the extra mails?
