Putty : How to copy/paste from/to putty?

Copy/paste what? Files? Isn't 'scp' available? http://www.computerhope.com/unix/scp.htm

Copy/Paste text to/from Putty.

Putty is much more practical/convenient because it has a graphical user interface with the possibility to save all the sessions (no need to remember them).

BTW, I read Google answers but nothing works (shift insert...)
