I Can't Copy/Paste/Edit on /usr/share/fonts

I can’t do anything in the location of /usr/share/fonts.

Although I am a root user, administrator.

How to get GUI copy/Paste on usr under file system.

Hello. Use the terminal with sudo to navigate through these restricted access folders. You could always change folder permissions using chmod/chown, but I don’t recommend that.

GUI?if u can run the file manager with sudo.
But again, as already said it’s preferred to use sudo and commands directly through terminal to do your work
