DiskBoss includes a built-in duplicate files finder, which provides a large number of advanced features and capabilities allowing one to identify and cleanup duplicate files on personal computers and enterprise storage systems. The duplicate files finder shows detected duplicates and allows one to delete duplicate files, replace duplicate files with links to originals or delete duplicates.

The user is provided with the ability to categorize and filter detected duplicate files by the file extension, category, file size, user name, last access time, etc. Moreover, DiskBoss allows one to generate various types of charts and export duplicates to HTML, XML, text and CSV reports.

The DiskBoss' duplicate files finder allows one to delete duplicate files, move duplicates to another directory or replace duplicates with links pointing to the original file in each specific set of duplicate files. In order to select a specific duplicates removal action for one or more sets of duplicate files, select the sets in the set list, press the right mouse button and select an appropriate duplicate files removal action.

Warning: There are many duplicate files in the Windows system directory, which are important for proper operation of the operating system. Removal of duplicate files located in the Windows system directory may permanently damage the operating system and render the computer completely non-functional.

By default, DiskBoss selects the oldest file in each set as the original file and all other files in the set as duplicates. In order to change that, select one or more sets, press the right mouse button and select the 'Select Oldest Files as Duplicates' menu item. Alternatively, open the set dialog, select any arbitrary file in the set as the original file, select an appropriate duplicates removal action that should be executed for this specific set and select one or more duplicate files in the set that the removal action should be applied to.

The DiskBoss' duplicate files finder allows one to categorize and filter duplicate files by the file extension, category, size, user name, etc. The user is provided with the ability to apply multiple file filters, display specific types of duplicate files and apply duplicate files removal actions to or export reports showing filtered files only. In order to set one or more file filters, select an appropriate type of file categories in the categories combo box, select one or more file filters in the filters view, press the right mouse button and select the 'Apply Selected Filters' menu item.

With active file filters, DiskBoss shows duplicate files matching the selected filters, exports reports showing matching files only and significantly simplifies selection of duplicates removal actions for specific file types or file categories. In order to clear the selected file filters, just press the 'Clear' button located on the right side of the categories selector.

The duplicate files finder allows one to display charts showing the amount of wasted disk space and the number of duplicate files per extension, file type, file size, user name, etc. In order to open the charts dialog, press the 'Charts' button located on the dialog's toolbar. The charts dialog displays information for the displayed duplicate files and the currently selected categories of duplicate files. In order to display a chart for another category of duplicates, select an appropriate category in the categories combo box and then open the charts dialog.

DiskBoss allows one to save lists of detected duplicate files to HTML, XML, text and Excel CSV reports. In addition, the user is provided with the ability to save DiskBoss' native reports, which preserve all information about each specific duplicate files detection operation and may be imported to an SQL database using DiskBoss Ultimate.

One of the most powerful capabilities of DiskBoss is the ability to perform disk analysis and file management operations on files matching user-specified criteria. In order to be able focus of specific types of duplicate files, the user is provided with the ability to define one or more file matching rules specifying files that should be processed by the DiskBoss' duplicate file finder. Files not matching the specified rules, will be just skipped from the duplicate files detection process.

In addition, IT and storage administrators are provided with the ability to submit reports from multiple servers and desktop computers to a centralized SQL database allowing one to analyze the disk space wasted on duplicate files across the entire enterprise.

DiskBoss Ultimate and DiskBoss Server provide the ability to analyze duplicate files owned by multiple users and detected on one or more servers or desktop computers and display charts showing the amount of wasted disk space and the number of duplicate files per user and/or per host.

Finally, DiskBoss Ultimate and DiskBoss Server provide the user with the ability to automatically execute one or more duplicate files removal actions for files matching user-specified rules. In order to define one or more automatic duplicates removal actions, open the operation dialog, select the 'Actions' tab and press the 'Add' button.

On the 'Action' dialog select the original file detection mode, an appropriate duplicates removal action and specify one or more file matching rules defining files the action should be applied to. During runtime, DiskBoss will process detected duplicate files, apply the specified file matching rules, detect the original file and execute the duplicates removal actions for files matching the specified rules and policies.
