Shares
When settings are set to default, each USB device connected to the Zyxel Device is given a folder, 
called a “share”. If a USB hard drive connected to the Zyxel Device has more than one partition, then 
each partition will be allocated a share. You can also configure a “share” to be a sub-folder or file on 
the USB device.
File Systems
A file system is a way of storing and organizing files on your hard drive and storage device. Often 
different operating systems such as Windows or Linux have different file systems. The file sharing feature 
on your Zyxel Device supports File Allocation Table (FAT) and FAT32.
Common Internet File System
The Zyxel Device uses Common Internet File System (CIFS) protocol for its file sharing functions. CIFS 
compatible computers can access the USB file storage devices connected to the Zyxel Device. CIFS 
protocol is supported on Microsoft Windows, Linux Samba and other operating systems (refer to your 
systems specifications for CIFS compatibility).
12.1.2  Before You Begin
Make sure the Zyxel Device is connected to your network and turned on.
1 Connect the USB device to one of the Zyxel Device’s USB port. Make sure the Zyxel Device is connected 
to your network.
2 The Zyxel Device detects the USB device and makes its contents available for browsing. If you are 
connecting a USB hard drive that comes with an external power supply, make sure it is connected to an 
appropriate power source that is on.
Note: If your USB device cannot be detected by the Zyxel Device, see the troubleshooting for 
suggestions.
