Creating the folder
First, let's talk about how we can enable these "magical folders" that perform actions on files dropped within them. For this example, I'll show you how to make a folder on your desktop that, when a file gets dropped into it, will display a dialog letting your know that the file was placed there. Start by creating a regular folder on the desktop; you can either right-click and select "New Folder," or select "New Folder" from the Finder's File menu.
A menu will roll down asking you to specify an Apple-created script. We'll choose the "add - new item alert.scpt." This script will alert the user via a dialog when an item is placed in a specific folder. In the right hand side of the window you will now notice that the add script has been placed there. You can add multiple scripts to a folder action and they will be performed in consecutive order until the end of the list is reached. Once you have created the actions, you can close the window.
It's just a drag to the left.... activating the scripts
I tend to use this same folder action for my Drop Box located in the public directory of my user account. Since this folder is available to the public via a LAN connection, I am alerted whenever someone drops a file into it. There are literally tons of uses for the add file folder action. Why not play around with it and let us know your favorite uses for it?
Coming up in Part II: we'll go through Apple's supplied folder scripts and identify which of them provide the maximum automation payoff.
