What is an IWD file?

IWD files mostly belong to 7-Zip. IWD files are mainly used as game data archives in popular Call of Duty titles. They use the ZIP format internally, which means the file bundles various assets such as maps, models, textures, audio files, and scripts into a single package.
If you have an IWD file, you can open it with an archive manager like 7-Zip or WinRAR. Many users change the file extension to .zip so that they can easily extract and view the contents.

This file type is primarily found in games like Call of Duty: World at War and Call of Duty 4.

In a less common scenario, the IWD extension is used for ID card design files in software by Datacard Preface.

FilExt.com note: For more details on the game usage, visit the Call of Duty website, and for ID card design information, check the page at Entrust.
