By default, DupScout detects duplicate files using generic settings, which should be appropriate for most users. In addition, power computer users are provided with a number of configuration options allowing one to customize duplicates detection process for user specific needs.

In order to customize the duplicates detection process, open the profile dialog and select the 'Advanced' options tab. The advanced options tab allows one to control the default report title, the type of the signature used to detect duplicate files, the maximum number of duplicate file sets to report about and the file scanning filter, which may be used to limit the duplicate files detection process to specific file types.

• Report Title - this parameter sets the default report title to use when exporting HTML, Excel CSV or text reports.
• Signature Type - this parameter sets the type of the algorithm that should be used to compare files: MD5, SHA1 or SHA256. The SHA256 algorithm is the most reliable one and it is used by default. The MD5 and SHA1 algorithms are significantly faster, but less reliable.
• Max Dup File Sets - this parameter controls the maximum number of duplicate file sets displayed in the results list. After finishing the search process, DupScout will sort all the detected duplicate file sets by the amount of the wasted storage space and display the top X duplicate file sets as specified by this parameter (default is 1000).
• File Scanning Filter - this parameter (DupScout Pro only) allows one to specify a file scanning filter to be used during the duplicate files search. The file scanning filter provides the user with the ability to limit the duplicates search process to a specific file type or a custom file set matching the specified file scanning filter. For example, in order to search for duplicate JPEG images only, set the file scanning filter to '*.jpg'. This file scanning filter will match all files with the extension JPG (JPEG Images) and skip all other files.
