How to gain a permission for copy/pasting for system folders?

Question

I've been using Windows OS before, and it's a bit hard for me copying and pasting to Ubuntu's system folders so. If i drag file or folder into File system folders, I'm getting "permission denied" error. Is there any way to copy/paste file/folders easily (not by Terminal)? Thanks in advance

Solution

If you press Alt + F2 to get to the Run Application screen, and then type gksudo nautilus it will ask for your password and drop you into a nautilus session where you can drag drop into system folders, however, be very careful since you can destroy your system if you're not careful.
