used to copy all the files that exits in a main root folder (say ALL FILES) ,even if the files are in the sub folders of that root folder, to a other folder ( EX FILES) where the program file exists.
paste the program file (python_paste.py) where the root folder exists and change the vales of the folder to root folder name on which you want to perform action and run the program. voilà ! your files are copied to the save as file.
