In general, this duplicate file finder is also safe to use. Designed with safety in mind, it takes measures to prevent users from deleting files by mistake. It allows users to remove duplicates by sending them to the Recycle Bin (Windows) or Trash (Mac), making it easy to recover deleted files.
However, dupeGuru for Mac can’t safely deal with the duplicates in Photos on Mac.
The latest version of dupeGuru is 4.2.1, which was released on March 27, 2022. You can download dupeGuru for free from the official website or GitHub. Older versions are also available on GitHub.
It’s easy to install and uninstall dupeGuru. Just follow the traditional installation or uninstallation process.
Yes, it’s freeware. Initially released in 2004, dupeGuru was commercial until 2010 when Hardcoded Software announced that its apps went open source. It is now open source and totally free to use. There is no need to buy a license.
Its last paid version was 2.12.0 with a price tag of $19.95.
dupeGuru used to have three editions: dupeGuru, dupeGuru Music Edition and dupeGuru Picture Edition. Later they were packed in the same app.
dupeGuru offers three modes: Standard, Music and Picture. The Standard mode can scan for duplicate files by content or by filename (using the fuzzy matching algorithm).
The Music mode can compare audio files by filename, tag or content. It designed to find songs that are exactly the same or similar. In the test, it failed to find all the duplicates in my music library.
The Picture mode specializes in searching for duplicate image files. It can identify duplicates by content or EXIF timestamp. Also, you can set this mode to find similar photos. To do so, click the More Options button and then set the Filter Hardness slider to less than 100.
Easy to use and configure, dupeGuru does a good job of scanning PC and Mac for duplicate files. However, don’t use dupeGuru to find duplicate photos in Photos on Mac, because it will return false positives. And letting dupeGuru removing them will damage the Photos library. Mac users need duplicate file finder software that safely supports Photos.
Once scanning finishes, the Results tab will appear, listing all the found groups of duplicate files for you to view. If you want, you can save the scan results or export them to HTML or CSV.
Each group consists of the original file (marked in blue) and its exact duplicate(s) or near duplicate(s).
There are three additional view modes.
You can filter the scan results if needed. In the upper right corner of the Results tab, you can find a search box. For example, if you type “png” and hit enter, only PNG files will be shown.
To remove a file duplicate, you need to mark it for deletion first. To mark a duplicate, you need to select the checkbox next to it. You can mark unwanted duplicates one by one by hand. Or, you can use the Mark All option to do that automatically. It’s recommended to mark unwanted similar photos by hand.
With dupeGuru, there are two ways to remove marked duplicates. You can move them to the Recycle Bin (Windows) or Trash (Mac) or move them to a folder of your choice.
When you click Send Marked to Recycle Bin, the Deletion Options dialog box will pop up. You only need to click the Proceed button. This dialog box also comes with a Link deleted files option, and a removed file will be replaced by a link to the original file if you enable this option.

You can easily add folders to scan for and remove duplicate files. You can also have control over the scan and removal by customizing and taking advantage of the provided options.
It can find most duplicate files, but is easily outperformed by its paid counterparts. Although the developer claims that dupeGuru is easy to use without documentation, users may have problem understanding and using some of its features.
The biggest problem is that dupeGuru for Mac can’t properly find duplicates in Photos. It’s recommended to use an alternative with perfect support for Photos.
