What is primarily archived in a '.swc' file?

A '.swc' file is specifically designed to package ActionScript class definitions along with other resources such as metadata and assets necessary for building applications in Adobe Flash (now Adobe Animate). This file format helps developers streamline the process of sharing and reusing ActionScript code, as it can contain compiled classes and components that can be easily integrated into other projects.

The focus on ActionScript class definitions makes the '.swc' format especially useful for developers working with the Flash platform, as it allows for encapsulation of functionality that can be deployed in various environments. The inclusion of compiled code within this format enhances performance and reduces the need to manage multiple separate files for classes, thus facilitating more efficient project management.

In contrast, '.swc' files do not primarily store video content, audio clips, or image assets as their main purpose revolves around code and class definitions. While some assets may be included, such as linked images or fonts, these are secondary to the primary function of the file.
