The Find Duplicates button starts the search for duplicate files.
First, it detects all files in the directories which are listed in the folder list. Then, all these files are indexed, and finally, all the files are checked.
Files which are identical in content (same size and contents), but possibly have different filenames, file dates and locations, are displayed on the same line in the Identical Files pane. When hoovering over the file, all other individual file information is displayed in the File Info pane. Selected files are highlighted. Doubleclicking a file will execute the shell open function (for instance: open your viewer if it is an image).
The process of finding identical files can be time-consuming. Therefore, the application provides a Cancel button with which this process can be cancelled.
You can safely press the Delete Dialog Button during a scan, and delete files. The scan will continue after you close the dialog.
