What is a .aexpk file?

An .aexpk file is a compressed package designed to store assets for Apple's application development ecosystem. It's typically used by developers to bundle resources like images, sounds, and configuration files needed for their applications. These files are proprietary to Apple's development tools, meaning they are not meant for general user interaction or consumption. The primary purpose of the .aexpk format is efficient storage and transfer of development assets within the Apple development environment.
