How 2 change permissions for selected folders and files?

I need to change permissions for the folders and subdirectories to 777 and the files under them to 666. How can I manage that with a simple click?

When I selected the TOPfolder and set permissions to 666 for all files i the subdirectories - they have 666. After that I want to set 777 for ONLY folders in the subdirectories and keep the 666 value for the files.

After that I want to reverse all permission values back to original value.

Hello ..

This is not possible.
