Whenever my teenage daughter uses my Mac (a MBA running Mountain Lion), she visits Tumblr and downloads dozens of jpg and png files to my Desktop. So I told her not to, all to no avail. So I turned to Automator. I created a Folder Action, and the purpose of the folder action is to automatically move all image files to a sub-folder of My Documents, unless the file name begins with "Screen" (If I take a screenshot, I want to keep it on the Desktop). It works! Well, sometimes it works, and sometimes it does not. Most aggravating! Since it works, I can't figure out what I'm doing wrong, but since it doesn't always work, I must be doing something wrong. (By the way, I'm fine with doing this a different way). What I did was create a Folder Action for the Desktop Folder (not sub-folders). It goes like this: Filter Finder Items where: Name does not contain Screen Kind is image or Kind is Web Internet location Move (these) Finder Items to the sub-folder It's installed as a "Folder Action." It works, but only sometimes.
