Folder Actions

Folder actions were originally a classic Mac OS technology, but they were introduced into Mac OS X in Mac OS X 10.2 (Jaguar). A folder action allows you to “attach” scripts to a folder in the Finder. The scripts are triggered automatically whenever files and other Finder items are added to the folder or removed from it and whenever changes are made to the folder’s window. See Chapter 21, Folder Actions, for more information about this feature.

AppleScript Utility’s Set Up Actions button launches the Folder Actions Setup application for you. This is convenient if you have AppleScript Utility open. If you don’t, you can launch Folder Actions Setup by choosing Configure Folder Actions from the Folder Actions submenu in the Script menu or from the Finder contextual menu, or you can launch it simply by double-clicking Folder Actions Setup in Applications > AppleScript > Folder Actions Setup.
