What is a CACTION file? Conversion action performed by Automator, an Apple OS X program; bridges actions whose types of provided data ( AMProvides property) and accepted data ( AMAccepts ) do not match; installed in the same system directories ACTION files are located, e.g., /​System/​Library/​Automator folder ; users are usually unaware of this file because Automator converts between actions automatically and does not display the conversion actions.

More Information Automator enables the user to bypass programming normally required to create automations. The user can easily create .WORKFLOW documents by building individual actions into a complete task by dragging and dropping them into an Automator workflow. Automator gives the user the ability to repeat tasks in different programs, such as the Address Book, iCal and the Safari web browser. NOTE: Both CACTION and .ACTION files can be developed using Apple Xcode IDE.
