One thing’s for sure: Organizing your Mac’s files is no fun. If you’re fed up of regularly having to file and sort, let Hazel do the hard work for you. Getting started is super simple: Specify the folders you want it to keep an eye on, set a few rules, then let it work its magic.

Let’s say you want to organise your Downloads folder. You can move items based on their file type, name, date downloaded, the website you got them from, and much more. In a few seconds, your folder goes from cluttered to cleansed.

You can set it to rename, upload, tag, archive and open files on multiple criteria, and manage your Trash to boot. It integrates with Spotlight, Photos, Automator, AppleScript, and a host of other apps and systems. It’s the spring clean your Mac needs, done the easy way.
