Find Duplicate Files

Find Similar Files

1) Add the folder(s) to be scanned using "Add Folder" button (1)
Note: Self-scan can be disabled for a folder using the checkbox in front of the folder name. This will force the application not to compare the items inside with each other - they will be compared only with items in the other folders in the list.

2) Choose the scanning "Method" (2) to be used, e.g. to scan for 100% exact duplicates select "100% Equal Files" and to scan for similar files select Similar Files

3) For Similar Files method, adjust the "Similarity" (3) value. 95% is set as default and produces the best results for regular use. Lowering the similarity value will slower the scan speed and may produce false positives.

4) If filtering is necessary it should be applied prior to starting a scan using the "Filter" button on the toolbar.

5) Press "Start Scan" button (4)

After the scan process is finished the following screen is displayed:

Find duplicate files

Duplicate files are grouped together with different color. Depending on the "Auto Check" settings, the program automatically marks the files with older file dates. If files are un/checked manually, "Auto Check" button (1) or "Quick Check" (2) can be used to clear the changes.

After checking which files should be moved/copied or delete and choosing the corresponding operation (3) pressing the "Perform" button (4) will execute the selected operation.

The duplicates list supports multiple files selection and multiple files can be selected using the mouse and Ctrl/Shift keys. "Checked" and "selected" files are different terms and should not be confused. The selected files can be deleted from the list using the Delete key or deleted from the hard drive using the Shift+Delete key.
