Over time, we all build up a collection of duplicate files. Gemini 2 for Mac helps you clear out the clutter with ease and make more space on your hard drive. This Red Dot Design Award Winner is now only $12.99 (Orig. $19.99) via 9to5Toys Specials.

Finding and deleting duplicates by hand is a time-consuming business. But with Gemini 2, you can banish the unwanted copies in seconds. This stylish app compares photos and searches your iTunes library for identical files. You can then choose what you want to delete and what stays. To assist with your decision making, Gemini 2 provides a preview of duplicate photos.

You can make the process even quicker by switching on the Smart Select feature. The app learns what kind of files you tend to trash, and picks them out from the search results. Nothing is actually deleted — you always have the final say. In fact, you can easily restore any file with one click. Available in 12 languages, this highly rated app can make your Mac run more smoothly.

You can get Gemini 2 for $12.99 on one Mac, or get two licenses for only $19.99 (Orig. $39.90).
