10 Best Duplicate File Finders in 2020 (Free & Paid)

Cover image

A duplicate file finder is a tool that’s used to find duplicate files on a local computer or corporate network. This tool runs a deep search on your computer to compare duplicate files regardless of the filename. The list of duplicate files can either be removed, copied, or moved.

Duplicate files are a problem not only because they clutter your storage space. But also because they might cause unnecessary lags, especially when the specific file is large. Your computer system doesn’t come with an innate tool to handle these tasks. And it’s close to impossible to manually go through all your folders to pick and get rid of the duplicates.

Without a quality third-party Duplicate File Finder, your only option is running a search for a specific file and manually deleting the duplicates that appear. And not only is the method time consuming but it’s also inconvenient because you can’t do away with the duplicates unless you know the specific files to look for.

In this guide, I will help you find the best duplicate file finders for your exact needs. Let’s go!

Reviews of the 10 Best Duplicate File Finders

As stressed earlier, having a good Duplicate File Finder is important as it helps to free extra disk space while providing more space for the smooth running of your applications. This tool also speeds up indexing and reduces back up size and time.

So let’s now shed light on some of the best duplicate file finders available on the market today!

1. Gemini 2

Developed by the creators of the renowned CleanMyMac X, Gemini 2 is curated to dredge for redundant files and remove them to free space and enhance your computer’s performance. This software is arguably the best on the market for Mac users, thanks to its multi-purpose function. Unlike regular Duplicate File Finders which focus solely on your computer’s hard drive, Gemini 2 goes the extra mile to remove duplicates from external storage, cloud storage, and network storage. So, sit back and let the software remove the files from wherever they are.

Gemini 2

Gemini 2 features in-built smart algorithms that track and retain your choices. The program gives you a range of search options to improve the scan accuracy and enhance the effectiveness of the process. The customization function also allows for precise searching, especially when you have an idea of the specific file you wish to remove. By allowing you to key in the file type, name, file size, and location, Gemini 2 makes the process seamless and effective.

Furthermore, unlike a regular duplicate file finder that searches and automatically remove duplicate files that don’t belong, Gemini 2 provides you with the search results before executing the removal process. And while the software intelligently picks exact duplicates that are identical and with the same weight, the list of the results helps to instill the extra trust before removing the redundant files.

>> Tim’s Pro Tip; When using the software to scan your Mac, we recommend quitting other apps to avoid overheating. Gemini 2 is quite demanding to run concurrently with other apps.

  1. Mark

    Hi Tim,

    I know that there is a multitude of software for finding duplicates and it is difficult to know all them.
    I would just like to draw your attention to a brand new software: Duplicate Media Finder.

    As you are obviously looking for the “best duplicate file finder”, I would be really interested in knowing where you would place Duplicate Media Finder ;o))

  2. Don Morrison

    Thanks Tim! I’m looking at Easy Duplicate Finder, being a Windows and iOS user & photographer.. I found out, talking to another retired photographer, that compression is our biggest enemy, for example in every save of a jpg file. He saves everything in RAW FILE, and TIFF formats. The only way I see to keep my .JPGs is OLDEST FILE or original filtering. You’ll notice every save of those files becomes softer resolution to the point of downright blurry. Who filters those JPGs and saves as TIFF? Don

  3. Ashley

    Thank you very much for the review. I am a mac user and I’m definitely surprised not to find Duplicate File Finder by Nektony on your list. This app has a quite replete free mode and it’s Pro mode is cheaper than in Gemini 2, but has much more useful features. I think it’s great to add it to your list.
