If you are running out of storage space on your Mac, it might be time to install DaisyDisk. This award-winning app scans all the files on your Apple machine, meaning you can zap duplicates and oversized videos. You can currently grab the app for only $6.99 (Orig. $10) at 9to5Toys Specials.

We all have duplicates and long-forgotten installers lurking on our hard drives. Collectively, these files take up quite a lot of space — but they’re not always easy to track down. DaisyDisk for Mac helps you clear the clutter by listing every large file.

You probably wouldn’t expect a disk analyzer to win prizes for aesthetics, but DaisyDisk is one of the most stylish apps around. The colorful visualizations make it easy to spot oversized files, and you can delete them easily via the list below. The app works with your Mac HD, external drives, flash storage, and even with network-attached drives.

DaisyDisk is usually $9.99 in the Mac App Store, but you can download it now for just $6.99.
