Using AiDisk for File Sharing
AiDisk allows you to share files stored in a connected USB storage
device through the network.
Before using AiDisk, connect a USB storage device, such as a
USB hard disk or USB flash drive, to the USB .0 port on the rear
panel of your wireless router. The USB storage device should be
formatted and partitioned properly. Refer to the Plug-n-Share
Disk Support List for disk format, file and partition size at

To avoid data loss or damage to the USB storage device, always
follow the steps to safely remove your USB device.
