Gaining root access to file manager
 

Does anyone know how I can access areas of my file manager as root so I can save, write and transfer files to and from any area?

go to a command line and type

su

give your password when asked, and then type the name of your file manager

although beware - having a file manager open as root is dangerous!

Try logging on as root that works on some distros. Another suggestion is to use the terminal: su>>password then manually manager your files using

chmod a+w /path/file

to make files read & writeable for normal users to edit.
