About compiled clips and SWC files

A compiled clip is used to pre-compile complex symbols in a Flash document. For example, a movie clip with a lot of ActionScript code that doesn't change often could be turned into a compiled clip. As a result, both Test Movie and Publish would require less time to execute.

A SWC file is the file type for saving and distributing components. When you place a SWC file in the First Run\Components folder, the component appears in the Components panel. When you add a component to the Stage from the Components panel, a compiled clip symbol is added to the library.

For more information about SWC files, see Creating Components.
