MacKeeper - a single app for a clean and secure Mac this is a good third-party software to do that.
MacKeeper is absolutely the WORST software for any purpose. It is close to being malware, and many security experts consider it to be malware.
You can see where your storage is being used and manage it with Mac OS itself. Click on the Apple Menu, About this Mac, More Info, General, Storage and it will list all of the data on your drive. If you click on the i next to any entry it will list all of the files in that category, and you can select and delete the ones you don’t need.
There is also a GOOD, free, 3rd party app that is similar to the built in storage management, but slightly more user friendly, because it sorts all of your content in decreasing order of size: OmniDiskSweeper.
