A SWC file is an archive file for Flex components and other assets. SWC files contain a SWF file and a catalog.xml file. The SWF file inside the SWC file implements the compiled component or group of components and includes embedded resources as symbols. Flex applications extract the SWF file from a SWC file, and use the SWF file’s contents when the application refers to resources in that SWC file. The catalog.xml file lists of the contents of the component package and its individual components.
You compile SWC files by using the component compilers. These include the compc command-line compiler and the Flex Builder Library Project compiler. SWC files can be component libraries, RSLs, theme files, and resource bundles.
To include a SWC file in your application at compile time, it must be located in the library path.
