DaisyDisk is a utility for Mac OS X that analyses your hard disk usage on any drive connected to your computer and presents it in an easy to view way. Not only does DaisyDisk show you what’s using up space on your hard drive, but it also makes it easy to remove files that you don’t need by revealing them in the Finder.
When you open DaisyDisk, you can choose between any of your connected drives on your machine to scan. I scanned both my 120GB internal hard drive of my MacBook Pro laptop and the attached 2TB external hard drive. The scan of the 2TB drive took a few seconds, and the scan of my system drive was done in a little over a minute. After the scan of your drive has been completed, it becomes apparently obvious what sets DaisyDisk apart from any other hard disk usage analysers available on the market: the interface is stunning…
Your files are displayed using a ‘sunburst’ visualisation, with an accompanying list on the side of the window offering a key to the diagram. The visualisation not only shows where files are taking up most space, but is designed in such a way that the folder hierarchy of your drive is also displayed in a very easy to see way.
If you want to find out what’s taking up so much space in a particular folder or section of your drive, you can easily select it in the sidebar and show it in the Finder. If you find a large file you don’t need, you can then simply delete it. In addition to that, you can also preview file content by simply hitting the Space bar on your keyboard.
The simplicity of DaisyDisk is so ‘Apple’ in the design, and does the developers great credit, although you’ll have to fork out $19.95 if you want to buy it. For those looking for an easy to view disk analysis tool for Mac OS X, DaisyDisk is definitely a choice worth considering.
