You can free up a significant amount of storage space on your Mac if youclean up your Downloads folderon a regular basis,remove your old iPhoto library,erase Safari’s browsing dataandmove both your iTunes libraryandthe Photos library to an external hard drive, among other things.
But what about other files on your computer? WithDaisy Diskby Software Ambience, one ofApple’s Best of 2015Mac apps, it’s easy to identify the biggest storage hogs on your Mac.
The app makes the mundane takes of cleaning up the Mac’s storage easy and fun by giving your a nice visual breakdown on your disk space in the form of an interactive heat map. In this tutorial, you’ll learn how to reveal the biggest space wasters with DaisyDisk so you’re able to remove them and free up some additional storage on your Mac.
How to identify large files on your Mac with DaisyDisk
First of all, you will need to download DaisyDisk, which is available for$9.99 in the Mac App Store. Or,download a free trialdirectly from the official website.
Upon launching the app, just drag a disk icon from the desktop and drop it onto the DaisyDisk window. If you drop your boot volume, you may be prompted to type in your administrator password in order to give the app permission to use the disk.
You’ll get a great visual breakdown of the disk’s free and used space with all of your files and folders. The circular chart is interactive and updated in real time so it always reflects the true amount of free and used storage on the computer.
The app is incredibly fast: my mid-2013 MacBook Air’s 256GB SSD is half-full and it took DaisyDisk just a few seconds to fully scan its folder hierarchy and display the interactive file map. As you hover the mouse pointer over different sections of the chart, the appropriate folder is highlighted in the righthand column.
You can then click a section to get a breakdown of the files and sub-folders in that specific folder. By default, the app lists your biggest space hogs, which typically includes system folders likeUsers,LibraryandApplication. To display other items, click theSmaller Objectsoption.
The app’s interface couldn’t be simpler and it lets you identify and then dive into the largest folders and visually peruse the contents of your Mac. When you identify a folder that’s taking up a significant amount of storage, you’re able to drag it in the lower left corner of the app’s window to collect it.
DaisyDisk has helped me realize that I have more than 60 gigabytes of usable storage locked in the Mac’s Trashcan, which I haven’t emptied in a while. I also learned that various application caches inside the system’s Library folder are taking up more than three gigabytes of storage.
After collecting files that you’d like to delete, you may then empty the app’s built-in collection bin to permanently delete those items and free up storage space that was lost to these items. Don’t worry, DaisyDisk has built-in safeguards preventing your from deleting system files by accident.
Final thoughts
Last but not least, this app integrates OS X’s QuickLook feature—just select a file and press Space on the keyboard to preview it quickly, and can scan multiple disks in parallel at maximum speed.
I think it’s an easy-to-use utility with its unique circular overview of the storage hogs that does a terrific job of identifying unneeded and useless file you may have forgotten about, helping you free up your Mac’s storage in no time.
Highly recommended.
