.CDATA File

File extension cdata is used for certain files that contain sound effects/voice data and are located inside the BIG resource files of Command & Conquer 3, Red Alert 3 and possibly other strategy games from EA sharing the same game engine.

Note: CDATA also means character data, but this term is unrelated to this file type.

How to open:

Unless some kind of modding tool exist to work with these files, there is no way to open them manually.

How to convert:

Unfortunately, we do not know about any converter for .cdata files.
