FIFA World Cup game data
File type: Game file
A bly file extension identifies game data used by the FIFA World Cup football video game, released for Windows and video game consoles.
This file is associated with the Windows version of the game and is part of its internal data rather than a general-purpose document.

The bly file extension is associated with FIFA World Cup, a football simulation game for Microsoft Windows and various video game consoles.
A bly file stores data required by the game, including data used when loading game content. It is a proprietary, game-specific file intended to work with the corresponding FIFA World Cup release.
Open a bly file with the compatible Windows version of FIFA World Cup. The game reads the file as part of its own data and does not provide it as a document for separate viewing.
Do not edit or rename the file unless the game documentation specifically requires it, because doing so may prevent the game from loading its data.
A bly file is not intended for conversion to another format. It contains proprietary data for FIFA World Cup, and the game does not provide a standard export format for it.
To retain the data, keep the original file with the compatible game installation. Changing the file extension does not convert its contents.
