Is dupeGuru free?

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 totally free to use. There is no need to buy a license.

Its last paid version was 2.12.0. The price was $ 19.95.


Scan types, filters and performance

dupeGuru can efficiently scan for duplicate files thanks to its fuzzy matching algorithm. There used to be dupeGuru Music Edition and dupeGuru Picture Edition. They have been packed in the same app which now offers three modes: Standard, Music and Picture. The Standard mode will search for all duplicates regardless of file type. With Standard, users can choose from three scan types: Contents, Filename and Folder. There are also additional exclusive scan types for the other two modes.

dupeGuru scan modes

In Preferences, you can adjust the dupeGuru filter hardness. If you set the hardness level to 100, the app will only look for exact duplicates. Lower levels means looser matches, which means it will also find similar files.

dupeGuru preferences

You also can set the scan to ignore files smaller than the custom minimum size and to ignore subfolders in the selected folders.

In the test, we used dupe Guru and Cisdem Duplicate Finder for Mac to scan the same folder. dupeGuru found 265 duplicate items, whereas Cisdem Duplicate Finder found 361 duplicates with less time. Each time we used it to scan an entire hard drive, the app crashed.


View and select duplicate files found

Once scanning finishes, the dupeGuru Results window will show up, listing all the groups of duplicate files detected. Each group consists of the original file (marked in blue) and its exact (and almost exact) duplicates. The search boxes before the original files are disabled, which is a safety measure to prevent you from selecting and deleting the original ones. dupeGuru allows users to save and load scan results. Users can also export results to XHTML or CSV.

save results

You can sort the scan results by folder, size, file type, modification, match level, etc.

There are three other view modes.

  • Details Clicks Details, and a window will pop up showing you the file attribute of the selected file. If you select a duplicate file, it will also show the attribute of its original file, which helps you better compare them. If the dupeGuru is in Picture Mode, you can also preview images without having to open them with the associated app.
  • Dupes Only This view mode only list duplicates. Their respective original files will be hidden.
  • Delta If this mode is enabled, the numerical columns (size, dimensions and modification) will display the value differences (marked in orange) instead of the absolute values. For example, the original image is 182KB in size and its duplicate copy is 39KB, the Size column will show -144KB.

delta values

You can also filter the scan results by using dupeGuru’s filtering feature. In the upper right corner of the results window, you can find a search box. For example, if you type “png” and hit enter, only PNG files will be shown.

You can set dupeGuru to select all duplicate copies. But sometimes, you may still want to keep some of the duplicates or similar files. In such cases, you can manually select or unselect (individually or in batch) with the help of features like Dupes Only and Delta.


Duplicates removal

Now you can easily delete selected unwanted duplicates in a few clicks. Go to the top menu bar, select Actions > Send Marked to Trash. It’s that easy. You can also move selected duplicates to a folder of your choice.

remove duplicate files

In Preferences, you can set dupeGuru to directly delete files. But this option is not recommended. There is also the Link deleted files deletion option where the removed files will be replaced by a link to the original file.

On the Actions menu, there are also other actions which may be beneficial to users. One of them is Invoke Custom Command. This is more intended for advanced users who are familiar with command line.


Quick Summary

You can also have more control over the scan and removal by customizing and taking advantage of the more advanced settings.
