Preview images and reveal duplicates in the Finder

From each set of duplicate files, you can choose to select the ones you want to delete, or you can decide to hide certain items. Furthermore, you can reveal the selected file in your Finder and, if it is a supported image format, you also can preview the thumbnail directly from within Cisdem Duplicate Finder. Although Cisdem Duplicate Finder is easy to use and provides multiple sorting options, it does not provide its users with the possibility to automatically mark for deletion multiple duplicates based on various criteria, such as creation date or file size, audio quality and other related information.

You do get to select all the files and delete them at the same time, but if you have multiple duplicates for the same file and you need to decide which document you want to keep, you might find Cisdem Duplicate Finder to be useful if you have to deal with a small number of duplicate files since you have to go through the entire list and verify each selection. Bottom line, if you need to remove duplicate files from large folders with hundreds or thousands of files based on user-defined criteria, you might want to look for alternative solutions better suited to deal with the task.


Cisdem Duplicate Finder is an intuitive app that does the job well. While it could do with some more options, its accuracy and ease of use make it a great choice.
