The Duplicate Files tab is the main area you will be working with the duplicate files.
Once you have performed a scan you can now select files to delete, move or hard link. If in doubt, leave a file alone. To mark a file, in the 'Duplicate Files' tab click on the checkbox. You can also double click on a file to open it in it's native application for further investigation. A right-click pop-up menu is available from the list, with many more options.
Duplicate Files list
The list of all the duplicate files found. They are arranged in numbered 'Groups' (See group column). Each file in a group can be considered duplicates according to the criteria you set at the beginning of the scan. Marking (ticking/checking) a file specifies that you intend to remove (delete) that file later on.
The alternating background color is to help distinguish between groups.
There are lots of tools within Duplicate Cleaner to help you mark the files. You can right-click on a file and use the context menu for more actions. You can use the selection assistant as well.
Marking all the files in group may lead to all copies of a file being deleted. This helps prevent that by bringing up a list of any groups which have had all the files marked for removal. Selecting a group number and clicking 'Jump to Group' or double clicking will jump to the group in the list view.
This section displays and controls the current filtering on the duplicate files list.
Filters available include:
All - Show all duplicate files.
Marked - Show just marked files.
Not Marked - Show files not currently marked.
Group has Mark - Show groups which have at least one marked file
Group has no Marks - Show groups with no marked files.
Group has all Marked - Show groups with all files marked.
Other filters can be put in place from the Duplicate Files Popup Menu including path, file type and group filtering, and are displayed here. Clicking on the 'Clear other filters' button will remove these filters.
