One way to reclaim disk space on your Mac is to find and delete the large files and folders you no longer need. DiskWave is a Mac program that immediately analyzes the contents of your local drives and gives you easy access to the largest files and directories.
All you need to do is to select the folder or partition you wish to analyze and let the program complete the task. You can delete the large files and folder you no longer need on your Mac and preview files if necessary. The program also features an option to sort files in alphabetical order or based on their size.
Another important advantage is the fact that the application is also capable of analyzing disk space of any USB drive that's being inserted in your Mac. In my testing, the program immediately detected the inserted USB stick and displayed the necessary information.
Also, DiskWave used a very small amount of CPU resources while analyzing the selected drives and folders.
In conclusion, I think it's worth installing this utility on your Mac if you want to easily find out which files and folders use the most of your disk space. It's simple to use, efficient, and free.
