No computer system today is free of problems. Some are plagued with them right off the bat; others develop issues over time. Then there’s variation in the nature of system issues as well. Some problems arise because of poor programming of the operating system itself, while others may happen due to user issues. Thanks to effective quality control measures, coding issues are not that big a deal these days, since they’re either eliminated at the quality control stage, or fixed as they get identified.
User issues, however, are a different story altogether. Because they’re influenced by behavior and usage habits, they tend to pop up time and time again. And because a lot of human beings are inherently programmed a certain way, several user issues share a common ground. One such issue that you’ll find in almost all modern computer systems is the presence of duplicate files. What it simply means is having multiple copies of the same file, be it photos from your latest holiday or many copies of that Word document that you had been working on for some time.
Duplicate files is a problem because not only they clutter the hard drive, they also take up precious disk space, especially if the duplicates are of a particularly large file. Windows by default doesn’t come with a feature that can get rid of these pesky duplicates with ease. On the contrary, it can become quite a challenge to clean up duplicates because folder structures can get out of hand really fast. Luckily, there’s a good selection of third-party duplicate file finders out there that can do the job for you, and do it well. In this list, we take a look at some of the best duplicate file finders for Windows which you can use in 2019.
Note: When looking for duplicates in your system, always remember to limit your search to just your user folders and not “clean up” anything from the operating system’s folders, as that can negatively impact the stability and working of your computer.
Best Duplicate File Finders for Windows in 2020
Even after all these years, dupeGuru remains the best duplicate file finder and not just on Windows but also on macOS and Linux. It has got the best matching algorithm that looks for filenames, tags, attributes, metadata, and analyzes the content inside the file. For example, you can find duplicate images by scanning and comparing the similarity between images and not just filenames. You can further customize the matching engine and get duplicate results as you desire. Apart from that, dupeGuru is great with music files too. It comes with a special Music mode where you can scan songs in any format — FLAC, MP3, WAV, AAC, etc. — and find duplicates within minutes. It also shows music-specific information in a separate window so you can easily compare audio files side by side.
Having said all of that, the best part about dupeGuru is that it’s extremely fast in finding duplicate files and folders, thanks to its ‘fuzzy matching’ algorithm. Not to mention, dupeGuru offers you to filter results in multiple ways to weed out false duplicates (low threshold scans), and then you can easily move the files or delete them in a user-friendly interface. I would say if you are looking for a versatile and powerful duplicate file finder then dupeGuru is up for any task you throw at it.

XYplorer is a dedicated duplicate file finder; in fact, it’s a fully equipped and highly capable dual-pane file manager for Windows that comes with a “Dupes” detection feature. The option lies within the program’s Find Files feature where you further have the option of singling out duplicates in your search location. The reason it’s highly recommended is because of how it approaches duplicates – listing them by Name, Date Modified, Size and Content – and how it presents all duplicates found in grouping for easy cleaning. When finding duplicates by Content, you can either use MD5 or even do a byte-by-byte comparison, which, although slow, is the most accurate method out there that exists.
XYplorer is a paid software that costs $39.95 for a single-user license. It comes with a free trial, and there used to be a free version that has been discontinued as of January 2017. With a little search, you might still be able to find the free version online with the caveat of not getting any future updates.

4. Auslogics Duplicate File Finder
Auslogics Duplicate File Finder is a totally free solution that offers the same kind of features that several tools would charge you for. The program can scan your specified folders for duplicates and presents them in a fairly neat interface that makes it easy to manage the found culprits. There are various search parameters that you can define, including file types, minimum/maximum file size, names, creation dates and the like.
File content is matched based on MD5 checksum, but there’s no byte-by-byte comparison (MD5 is still fairly accurate for real-world use). You can also decide what happens to the duplicates that are found, whereby they can be sent to the recycle bin or rescue center, or deleted forever. This software, too, supports one-click operation, although with a less friendlier user interface. As far as free duplicate file finders for Windows go, this is the best option on the market. Heck, it even gives the paid options a run for their money.

6. Duplicate File Detective
Duplicate File Detective is another paid utility that offers more features than you can count. While the traditional options of finding and eliminating duplicate files is there just like you’d expect, the Detective takes it up a notch by adding the ability to scan network drives replacing removed duplicates with symbolic links to the originals (should you desire that), and providing a wealth of reporting options on detected duplicates including stating the owners of the duplicate files (very useful for MS Office files, for instance).
Reporting can also be done on file types and hash values, and reports can be exported or even scheduled for automatic emailing. In a nutshell, Duplicate Files Detective takes it a notch beyond just finding and removing duplicates all the way to keeping tabs on what those were and how they came to be. Oh, and the user interface is very similar to MS Office products, so you’ll feel right at home using this utility. This one is one of most trusted duplicate file finders for Windows.
Duplicate Files Detective is also one of the most expensive options out there, with a single user license starting at $55 with only minor updates included. Still, considering the unique features that it offers, the expense is worth it. There’s also a 15-day trial before you make the purchase.

CloneSpy is another free utility that, despite featuring a dated interface, does the job very well. The software works the same way as many paid solutions do, and even offers a byte-by-byte comparison for finding duplicates. It can even find duplicates for files between your local hard drive and network drives – something that’s hard to find even in paid solutions.
What’s more, CloneSpy also finds duplicates that are not exact matches, in that if you have two files that share the same name but a little different content (several versions of the same Excel report rings a bell?). It also allows you to not only rid the duplicates, but also generate reports of all dupes found in your scan. Comparisons can be done on file names and extensions, and you get an added option to find 0 byte files (empty files). As we noted earlier, the only area where CloneSpy falls short is the interface, but otherwise works really well.

While it works great for all file types, since this one doesn’t seem to support byte-by-byte comparison, I have mostly used for finding duplicate images and music files, and it worked great for those. The app comes with a 15-day free trial after which it costs
