MacPaw has released Gemini (http://macpaw.com/gemini), a Mac-only duplicate finder and cleaner. The software -- available at the Mac App store for US$4.99 for a limited time -- searches for and removes duplicate files including videos, music, images, documents and more.

System files are ignored by Gemini to ensure the stability of Mac OS X, according to MacPaw CEO Oleksandr Kosovan. Enhanced scanning algorithms allow Gemini to find the biggest duplicates so that a user could stop the scan and instantly clean a considerable amount of space if needed, he adds. The app can even find folders that have identical content.

Gemini includes such features as built-in preview, full screen support, core animation, drag 'n drop functionality and search and sorting possibilities.
With the Auto Select feature the software introduces a new way of cleaning duplicates in Mac OS X.

It allows user to avoid manual and boring selection of duplicates and perform this operation with a click of a button. Auto Select automatically selects duplicates by analyzing their parameters such as name, location, extension, dates of creation and modification, etc. Files identified as original copies are kept safe. If the algorithm cannot choose what instance of a file is duplicated, it leaves all of them at the user’s disposal.
