You don't need to use them all; simply select the nations that interest you the most.
The ddt are light files that allow you to have in your career all the players of the best teams in the world. They have been developed based on Pozzo DDT (already excellent) and have been expanded nation by country, adding new teams.
These files guarantee you to find the players of the championships you did not load; in this way you will not miss the best talents!
Below is a list of the nations present; each country will have the best teams of the 2 major leagues (e.g. Italy will have the best teams of Serie A and B, Premier and Championship for England).
