You have to change system properties before you can save files in the system folder.
In Es File explorer click the menu button and open tools. Scroll down to root explorer and turn it on. Then tap it and select Mount R/W. Change "/system" to be RW and hit OK.
Now any file in the system folder can be edited, written, saved, or deleted so be careful. Once you are finished editing repeat the process to mount "system" as RO. Depending on what you did you may need to reboot for changes to take effect.
