Open ENG File
An ENG extension file is a game engine used by various chess games.
What is a game engine?
A game engine is a set of programming routines and algorithms that allow the design, creation and operation of a video game and can be written in various languages.
In this case the ENG file contains functions and algorithms used by the computer to play against a user.
Chess engines can be updated or added to a chess program to provide new types of computer players, with various levels of difficulty.
For example, Fritz, one of the oldest and best-known computer-assisted chess game systems in the world, developed and maintained by ChessBase GmbH, makes use of the ENG engine, and it is even known that they can be loaded online via the web.
Fritz online is the only chess program in the world that works through the Internet browser.
The ENG files used by Fritz Desktop must be stored in
\Program Files\ChessBaseEngines.
ENG files are binary files and should not be attempted to be opened manually by the user.
