Choose System|File manager (Super User Mode) from the main menu. A window appears requesting the root password for your Linux system. 2. Enter the password. A file manager window appears. 3. Use this file manager window to browse to the file you want to change. 4. Use the procedure above (right-click and choose Properties) to update the file or directory information. 5. Close the file manager window to end the root-access session.
