Drag & Drop Renamer allows you to rename any file you want by patterns. You can drag and drop files to the main window of the program and even to its shortcut. At the main window you have the default action that executed when files are dropped into the program. When the extensions option is checked the default action is overrided by the extensions table. All the above rules applies in that table and preformed on the target file type.
