PGN file format is used by chess players for recording chess matches. PGN format offers transparent file structure divided into two parts: header and section that contains player moves along with comments.

PGN header contains such information such as event name, location, date, result, and player names. Sometimes it can hold statistical data for given game. PGN format was released in 1993, but PGN files with historical data before 1993 are also available.
