We have discussed using OmniDiskSweeper before here on multiple occasions, it’s a great tool. OmniDiskSweeper has long been one of my favorite free utilities available for the Mac, and I use it often for my own computer and when trying to figure out what’s eating the disk space of other Macs I may encounter.

Get OmniDiskSweeper from the developer (free).

The files are shown in descending order by size, so it’s very easy to figure out what’s eating up storage space.

OmniDiskSweeper is great and the interface is quite similar to using the Finder in Column view, making it very easy to navigate to large files and folders throughout the file system hierarchy. The free version of DaisyDisk is highly functional and will sweep your drive and allow simple quick access to any files or folders found (right-click on anything and choose ‘Show in Finder’), and you could get away with just using the free version if you wanted to, but if you enjoy DaisyDisk enough and find it to be a helpful companion to your Mac experience, the full version is money well spent. Get Daisy Disk from the developer here (free trial available, otherwise $10).In terms of visualization of your file data, DaisyDisk is superior to anything else available, and it’s also very fast. DaisyDiskĭaisyDisk is by far the most attractive storage analysis utility, with a beautiful and intuitive interface that makes finding disk clutter a matter of navigating an interactive colorful wheel. It’s a good idea to back up the Mac with Time Machine before using these apps if you’re planning on performing some mass file removal, it’s always better to be safe than sorry and lose files or have to reinstall Mac OS X if you deleted critical system files willy-nilly. We’ll cover three of the best and most popular disk space analysis tools available for the Mac, each of which is either free or offers a free trial version to give a good test run with.Ī big thing to remember with using these disk analyzer apps is that if you shouldn’t delete anything without discretion, as they sweep the entire drive and inevitably display system files, system folders, and other necessary components of Mac OS X and apps, along with personal documents and accumulated cruft.
