ChessBase shares a common directory for chess playing engines with programs like Fritz, Hiarcs, Shredder etc. This directory lies parallel to the program directories.
The program’s engine interface uses with the specifications of the current Windows version, for example Windows 7. This means that in future engines will no longer be stored in the folder /Program Files/ChessBase/Engines, they will be stored in /Program Files/CommonFiles/ChessBase/Engines.
Apart from this the new engines now have the extension *.engine.
After the installation you will find the Fritz engine and the current version of Crafty in the new folder. The chess engines of earlier program versions will still be in the folder /Program Files/ChessBase/Engines.
What do these changes mean for the user? The answer is simple: nothing at all. All the engines can still be used by Chessbase. This is true for recent engines as well as for older chess engines like Fritz 7 and Shredder 7.
UCI engines can be used wherever they are, in any folder or any disk on the computer. The configuration files with the extension *.uci are always saved in the folder /Documents and Settings/Username/Application Data/ChessBase/Engines.UCI.
When you install new ChessBase programs the engines are automatically put into the Engines directory.
