In order to minimize accidental removals of important files, DupScout implements a three- stage cleanup process with an actions preview dialog allowing one to carefully select and confirm cleanup actions that should be executed. Once finished selecting duplicate files that should be removed and cleanup actions to be used for each specific duplicate files set, press the 'Preview' button located on the main toolbar.

The actions preview dialog will display a list of all cleanup actions that should be performed and allow one to select/unselect each specific cleanup action. After carefully reviewing all the selected cleanup actions, press the 'Execute' button to actually cleanup all the selected duplicate files.

Typically, there are lots of duplicate files in the Windows system directory, which are critical for the proper operation of the operating system. All duplicate files located in the Windows system directory and other application specific directories cannot be removed and it is highly recommended to avoid touching these files.
