Please write your opinions and give some links for it

ChessBase 8/9/10 is a good choice to find and delete duplicate games

Best,
Sedat

A few useful links:

->"5. Clean large PGN Files: The database program CDB among others has a feature of 'Cleaning' a large PGN file. ... At the same time CDB can clean your duplicate games (twins) in a given PGN file. (etc...)

>Ok, I forgot that Scid treats PGNs as read only, and so you have to export it to a Scid Database, delete twin games and then export as PGN.


So:

Do File > New and name your new .si3 file

File > Open and select the file you created

File > Open and select your PGN

Windows > Database Switcher

Now, on the new window, drag the PGN into the white rectangle so the games are added to the Scid database.

Now, right click the PGN and close it.

And now you can do the delete twins thing. After that, just export back to PGN:

Tools > Export All Filter Games > Export Filter to PGN file

And you are done!

Also, guess what, the file you attached has no duplicate games  - But this may prove useful when you're managing 1000 games...
