The lng file extension is used mostly by multi-language applications and programs for storing separate language data for each language or sometimes all languages in one file.
Used in numerous programs. File formats may vary, but contains user interface strings and program menus etc. for specified language. File name before extension mostly contains language name e.g. czech.lng etc.
Also used in some games for their localization files.
LNG files are mostly in plain text format that can be viewed by basic text editor, or some common database file format.
Generally, there is no way how language files can be converted. However some might be opened using a text editor and data exported out of it.

Crysis was developed by Crytek for Microsoft Windows. Its LNG files store language-related data used by the game, such as localized text and messages.
The files are part of the Crysis installation and work together with the game's other resource files. They are not general-purpose language documents, and their contents may not be useful outside Crysis.
Install and run Crysis on Microsoft Windows to use a Crysis LNG file. The game normally loads the file automatically from its installation or game-data folders.
There is no need to open the file separately. A text editor may show unreadable or incomplete content and should not be used to modify the file unless the purpose is game modification.
A Crysis LNG file cannot be meaningfully converted to a common document or language-file format. It is game data designed for use by Crysis.
Keep the original file with the Crysis installation. Changing its extension or converting it may prevent the game from loading the associated language data.
