Cisdem Duplicate Finder for Windows main features
1. Find all types of duplicate files
This Windows duplicate file finder can find duplicate photos, videos, songs, documents, archives and other types of duplicate files. It accurately identifies duplicate files by content (regardless of filename). It also offers a way to identify duplicate files by filename and size.

2. Find duplicate folders
It can identify duplicate folders by content. If two or multiple folders are exactly the same regardless of folder name, they are a set of duplicate folders.

3. Also detect similar photos
It can also find near-duplicate photos (aka similar photos), such as photos that look the same but have different resolutions, file sizes or formats, and photos that look similar. Users are provided with options to adjust similarity thresholds for comparing images and tweak detection.

It groups them together for users to easily keep the best shots and get rid of the unnecessary ones.

4. Find duplicate files in and across locations, internal or external
This duplicate file finder for Windows can find duplicate files in and across folders/drives. In addition to a computer’s internal hard drive, it supports external hard drives, USB flash drives, SD cards and other external storage devices.

It can even help users get rid of duplicate files in cloud storage services such as Google Drive and OneDrive.

5. Let users view, sort, and filter scan results
Cisdem Duplicate Finder displays the duplicate files and similar images that have been found under the All tab in the results window. Users can also view them by file type. For example, the Images tab only displays duplicate and similar images. The built-in image preview feature allows users to preview duplicate photos side by side.

Users can also sort scan and filter scan results as needed, and there are multiple sorting/filtering options.

6. Automatically select duplicate files for users to delete with a click
In each set of duplicate files, Cisdem Duplicate Finder automatically and smartly selects all but one file for deletion. It also provides multiple selection rules (such as Select Newest) to help users mass select. Or, users can select or deselect by hand.

7. Offer three ways to delete duplicates
