Ah, sorry I think I might have misunderstood where the font files were located. Using the cp command in linux is pretty much the same as using copy in windows. Usage is: cp /path/where/stuff/is/now/file.txt /path/where/stuff/is/being/copied/to/
You can probably figure out how to use it to your need now. Another option is to open a filemanager as root. As root in a terminal, enter the command for your filemanager (examples: konqueror , thunar , pcmanfm -t ). You should then be able to copy the files that way.
