The copy file action will copy the passed file to a specified location. Use target directory to specify the directory where you want to copy the file and in the name pattern field you can either keep the file name the same or specify the new name for your copied file.
By default the name is set to [filename] which refers to the name of your file before the copy. For the name pattern you can leave the file name the same, replace the file name entirely or if you want to append it you can simply add text after [filename]. So if your source file is named “Weekend_Performance” and you use the name pattern [filename]_copy, your copied file will be named Weekend_Performance_copy.
