Find Duplicate Files
DiffDog enables you to locate duplicate files in a directory. Only items with the same names and contents are considered duplicates.
To search for duplicate files in a directory, take the steps below:
1.Click the 
toolbar command. Alternatively, select the menu item File | Find Duplicate Files. A new Find Duplicate Files window will open.
2.Supply the path to a directory that you want to search for duplicates. You can do this in any of the following ways:
▪By typing the path in the text field and clicking the 
(Apply) button or Enter.
▪By selecting the relevant path from the drop-down list of the text field.
▪By clicking the 
(Open) button and selecting the relevant path. When you click the Open button, you can browse for local or remote directories. To select a remote directory, click Switch to URL. This will open the Browse for Web dialog, in which you will need to supply the URL and, if applicable, the identification details. For more information, see Switch to URL.
3.The contents of the directory will be displayed. In case the 
(Autostart Comparison) toolbar command is toggled off, launch the Find Duplicate Files functionality by pressing the 
toolbar command or F5. You can now browse through the list of duplicates, copy their names and paths, and delete them if necessary. You can also filter out empty directories and files without duplicates, by clicking the corresponding toolbar commands (described below).

Table structure and duplicate management
The contents of a directory are displayed in tabular format. The table has the following columns: <Name>, Paths of Duplicate Files, Size, and Last Modified. If a file has duplicates, the links to them will be shown. Clicking a link forwards you to the corresponding duplicate.
When you click on the name of a file that has duplicates, the file and its duplicates will be shown in red (screenshot above). When you right-click a file, you can perform the following actions:
•Copy the file name
•Copy the full path to the file
•Delete the file (which is also possible via the toolbar and the Delete key)

You can configure various settings related to the handling of duplicates, such as delete options and notifications. For details, see DiffDog Options.
