An 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.[1][2] SWC files can be generated by the Adobe Flash Professional authoring tool, and by Flash Builder (or its companion compiler MXMLC).[3] They are sometimes referred to as class libraries and cannot be directly executed by the Flash Player.
SWC code libraries are typically included in an ActionScript 3 project, and compiled into the final SWF file alongside the developer's program, by the ActionScript 3 compiler. Only the classes that have been used by the project (and their dependencies) are transferred into the resulting SWF file.
