Hazel from Noodlesoft has been one of my software picks in the past, and the latest version also deserves a spot on the list.
Hazel is a workflow automation tool that you can use to monitor one or more folders. Using rules you create, Hazel can act on any defined event and perform a defined action. For example, you can have Hazel monitor your Downloads folder. When you download an image, Hazel can automatically move it to another folder; perhaps your Pictures folder. You can set up a similar filing system for movies, PDFs, music, and other files.
One of my favorite uses for Hazel is to monitor a public folder that I set up. Whenever a new file or folder is added to the folder, Hazel displays an onscreen alert to bring it to my attention.
Hazel is driven by rules, which are created in much the same way as Apple Mail rules. In fact, if you've ever created a Mail rule, you'll take to Hazel right away. Even if you've never created a rule, you'll discover that the process is straightforward and easy to master.
Hazel is a handy automated housekeeper that can save you time and trouble by keeping your Mac organized.
Hazel is $25.00. A 14-day demo is available.
