DupScout is capable of detecting duplicate files in a number of disks, directories or network shares. In order to detect duplicate files in multiple locations, press the 'Manage Profile' button, which is located on the right side of the profile selector combo box and specify all the disks, directories and/or network shares that should be processed.

By default, DupScout will process all the specified locations sequentially, one after one. When processing directories located on different physical disks or different computers, it may be more effective to process all the specified locations simultaneously.

In order to process all the specified locations in parallel, open the profile dialog, select the 'Advanced' tab and set the 'File Scanning Mode' option to 'Parallel'.
