What is a .IWA file?
The .IWA file extension stands for iWork Archive File, which is a type of file used by Apple's iWork suite, including Pages, Numbers, and Keynote. These applications are part of the operating system on Apple devices. The .IWA file is essentially a container that holds various components of an iWork document, such as theme style sheets, tables, and metadata. These components are stored in a format called a Protobuf stream, which organizes the data in a structured way to make it easier and faster to handle, especially on devices with limited memory like iPhones and iPads.
The data in these files is compressed using Snappy compression, a method developed by Google that is known for its high speed in both compressing and decompressing data. This makes it very efficient for saving space without slowing down the device when opening files.
The .IWA files are found inside a file called Index.zip, which is part of the iWork document bundle. This new method of storing data replaces the older XML-based format that iWork previously used. The change was made to improve performance on iOS devices and to enhance the sharing of documents through iCloud.
To open an .IWA file, you can use any of the iWork applications—Pages, Numbers, or Keynote—depending on the content of the file. These applications automatically handle the opening and management of .IWA files as part of their operation.
