Setting the root directory of FTP server to be the root directory of my android phone

[Android Central Question]

I have created an FTP server on my mobile phone using ES File Explorer.
In the explorer, I have set the root directory to "/".
However, when I view these files from my computer, Only the Sd card folder appears. Furthurmore, when i set the root directory to something like "/system/" the following error occurs.

An error occurred opening that folder on the FTP Server.
Make sure you have permission to access that folder.

I have also tried FTP using another client (Wifi FTP Server) and the same error occurs.

How may I give my PC the ability to access the rest of the folders in the root directory? (such as system or dev)

When on your phone, do you have access to these system folders?
Normally this requires you to root the device.
