The IWZ file extension belongs to the Developer Files category like 1205 other extensions. The popular software that supports IWZ files is InstallShield created by Flexera Software, Inc. Check the developer’s site for more on the software and IWZ files.
To open an unknown file like an IWZ file, first install software that supports it. If that doesn’t work, check the IWZ file for errors. Files with .iwz extensions are used by the MagicItem plugin for the Content Management Utility. The .iwz file type is not meant to be opened directly. It’s usually internal caches or temporary files.
The IWZ file extension can associate with several file types. Most often, it associates with the InstallShield Express 2 Project Format. IWZ files support Windows operating systems. The IWZ files store information to assemble package installations for the old Express InstallShield versions.
When double-clicking an IWZ file in Windows, if the operating system does not recognize the .iwz extension, you will get an error to select an app to open the file. This means Windows does not have a default program associated with the .iwz file type.
To associate the IWZ file extension with software, either edit the Windows Registry or right-click on the IWZ file, choose “Open With,” then choose an application that supports .iwz files. That will associate the program with the .iwz file type.
