Adobe SWC file

An Adobe SWC file is a package of precompiled Flash symbols and ActionScript code that allows a Flash or Flex developer to distribute classes and assets, or to avoid recompiling symbols and code that will not change. SWC files can be generated by the Flash authoring tool, and by Flex. They are sometimes referred to as class libraries and cannot be directly executed by the Flash Player.
An uncompressed SWC file contains at least a catalog.xml file, and a SWF file, usually named "library.swf". It may also contain other files, such as CSS files. The catalog contains a list of the ActionScript classes contained in the library, their dependencies, and modification dates.
This is a simple example of a catalog.xml for a SWC created in Flash CS4 which contains two sounds.
