DaisyDisk Review: A Flower-Powered Disk Visualizer

Often, throughout the life of a computer, the hard drive slowly fills with all manner of things: music, movies, preferences, support files, and so on. At a certain point this gets to be too much, and a user must clean house. But in order to do so, she must first discover which are the files that are taking up the most unnecessary space, and where they are. This is where disk visualizers like DaisyDisk come in. While it is nothing special, DaisyDisk is a perfectly competent and very aesthetic application for dealing with this problem.

This application is by no means the only visualizer out there. The problem of finding space on your Mac has been around for almost as long as the computers themselves have. DaisyDisk is, however, one of the best-looking visualizers on the market. Instead of showing files as simple rectangles, or even as a list, DaisyDisk shows all files as radiating outwards from the parent folder (marked with the full size of the folder, in the middle). This is where the name DaisyDisk presumably comes from, as the end result vaguely resembles a flower, although it is more similar to a pie chart, with the size of each file’s wedge based on how large it is.

The application presents its data in a format that is incredibly easy to understand. Once it is opened, it presents the user with a list of the various hard drives on the computer, with a bar displaying how full or empty the drive is (which changes color from green to red as more space is filled) Once a hard drive is picked, the disk is scanned (remarkably quickly compared to other visualizers), and navigation through the results, for the most part, is also very user-friendly. One simply clicks on the folder they want to explore either in the list or in the graphic and that folder slides into the center with a nice animation. This can be done indefinitely, drilling down (or outward, as the case may be) into smaller and smaller folders until the space-hogging culprit can be found. The path to the current folder is displayed at the top of the window, and if the center is clicked on, the parent folder opens, allowing easy access backwards. This can also be accomplished by a keyboard shortcut.

This app offers little more than a pretty interface. There are literally no preferences, no options to customize color, layout, even canceling the transparent background which can be a little annoying at times. It also fails to allow for what can often be the most useful tool in any visualizer a delete option. For the most part, people use this kind of application to find files they can remove to free up space. However, with DaisyDisk, once you find the file, you must right-click on it to open it in the finder, and then delete it manually. DaisyDisk does have a few features that beat out the competition the most useful being integration with Apple’s Quick Look. Once a file is clicked on, a user simply presses space bar to hear the audio, see the video or text, which is a great way to see if you really need a file or what it is. But again, if you decide it is unnecessary, you still have to go to the Finder to delete it.

There is also no help available in the application. While it is a very simple program, it is not simple enough  to warrant no aid at all. The Quick Look integration, for example, I found out by accident. There is one option in the menu to scan as a Super-User, presumably to find invisible and hidden files, but this is not explained anywhere. The “Back” button next to the file path also does not function as one might think: instead of moving up a file path, it moves to the last view you were at, acting more like a web browser than a file browser. Despite being a fully released product, it is clear that this is still a work in progress. Besides these omissions and flaws, one of the few menu options that does exist is to submit Feedback to the developers. Hopefully they will quickly respond and change the options that need changing.

DaisyDisk is not a necessary application, nor is it a perfect one. However, for a visually appealing way of discovering the files on your hard drive, a user needs to look no further. While not necessarily the most useful visualizer, DaisyDisk is fun to play with and look at, as the animations are smooth, the colors varied, and the interface simple. DaisyDisk retails for the slightly expensive price of $19.95, and you can download a free 15-day trial from its website.
