DaisyDisk 4.3

This program is a disk usage utility that helps you scan the contents of your drives and learn which files occupy large chunks of your memory. You can use this application if you're dealing with insufficient disk space and wish to reclaim memory with minimum effort.

DaisyDisk features an intuitive and nicely-designed interface, supports drag-and-drop actions, and has simple to configure settings. So, you don't need much computer experience in order to work with this program on your Mac.

In my testing, the program took less than one minute (45 seconds to be precise) to scan a 300 GB drive. So, DaisyDisk works pretty fast, even when scanning large local drives or external storage devices.

Another important advantage is that it can identify and scan various types of storage devices. You can scan the contents of Macintosh hard drives, network storage devices, USB sticks, etc.

Furthermore, this version comes with many bug fixes and is localized in two additional languages (Chinese and Spanish).

All in all, I can't find any reasons why you shouldn't buy this program for your Mac. It might prove to be of good use if you're searching for a simple solution for identifying and deleting large, unnecessary files from your computer.
