This is a simple tutorial, but if you have difficulties, questions, or doubts you should read: All About Duplicate Cleaner in Windows 11, 10, 8, 7
That article will let you learn all the basics of our duplicate finder tools and let you learn how to confidently get rid of duplicates.

1) Add the folder(s) that will be scanned using "Add Folder" button (1) or drag and drop them inside the application from Windows Explorer.
Note: Folders can be excluded from "Auto-check" and "Self scan" using the check boxes in front of the folder name. Reference the help file for more details.

2) If you want to find all duplicates then you do not need to alter the check boxes in front of the folder names. Check the first column in the folders list for the folders that you want to be excluded from the Auto-check functionality (2). Check the second column if you want to disable a folder from scanning for duplicates inside itself. (The second option is available only in Pro and Corporate versions of the program). Read more about these features here: How to exclude folders form auto-check.

3) Select "Visual Compare" method from the drop down list (3).
Note: "CRC32 Checksum" method does not scan images for visual similarity. Using this method only 100% binary equal images can be found. "File Size" method will find duplicates with equal file sizes.

4) Adjust the "Similarity" spin button to the desired value (4). The default similarity value is 95%. It is finely tweaked and produces the best results for common images.
Note: The similarity value is used only if the selected method is "Visual Compare".

5) The "Cache" drop down list (5) is set to DEFAULT and you should not change that setting if you are a regular user. The cache system stores data for already scanned images and improves performance for consequent scans. The cache is extremely fast and compact.

6) Before starting the scan process filtering can be applied based on various properties using the Filter tool button (6)
