DaisyDisk v2.1.1 Mac OS X

DaisyDisk allows you to visualize your disk usage and free up disk space by quickly finding and deleting big unused files. The program scans your disk and displays its content as a sector diagram where the biggest files and folders at once become obvious. To drill down to a folder, just click on a segment. To bubble up, click in the center. Move the mouse over the diagram and see the name and path of each file, and enclosed files (if any). Hit Space to quickly preview file content, without launching another application. In this way, walk around your disk and drag-and-drop all unneeded files into the collector. Expand the collector to check its contents. When done, clean it up with a single click.
Why DaisyDisk
No matter how large your disks are, the amounts of data you store on them grow too fast. You can ease your life for a while by using one of automatic "cleaners" to save a few hundred megabytes or even a few gigabytes but very soon you'll face the same problem. We propose a better solution: find out real space wasters and remove them. Fast and easy. DaisyDisk scans your disks and display them in a form of the interactive visual map, so you can find out where the space have gone, preview and delete large files and folders you no longer need. You can find out a long ago forgotten virtual machine image, huge cache file or a DVD movie rip you wanted to see during last year's vacation. It's way more efficient than spending hours on manually sorting downloads folder or guessing how come your Mac drive has no free space when you need it most. There're much better uses to your disks than carrying useless data.
Details do matter
DaisyDisk is not only visually appealing, it's also very easy to use. Once scanned, your disk is displayed as sunburst map, a very visual representation of all your files and folders. We have put many efforts into improving original sunburst map and the application's interface to ensure it leaves competition far behind. Consistent coloring and familiar navigation makes sure you won't get lost in data debris, fine-tuned disk map provides relevant information and preview is right when you need it. Animated transitions are not just eye candy, they improve navigation. There's much more than meets the eye.
All disks at a glance
DaisyDisk gives you a perfect overview of all volumes currently mounted, be it internal disk, USB thumbstick, FireWire drive, network or even virtual disk mounted with FUSE. Mount disk images, attach external drives and they're immediately displayed in DaisyDisk's list. Add, delete files, unmount disks... all the changes are real time, so you always know which volumes are mounted and how much free space you have on each of them. You can also get volume info and eject volumes from within the application.
Lightning fast
Modern hard disks can be as big as several terabytes and contain millions of files and folders. Scanning such amounts of data can take significant time even on modern hardware as disk speed cannot catch up to the growth of the capacity. We have fine-tuned our scanning engine so disk analysis runs as fast as possible. As a result, DaisyDisk outperforms competing products in scan speed by up to 50%. Hey, DaisyDisk won't even choke on Time Machine disks which causes many "disk scanners" to freeze or crash.
