The following figure illustrates how copying files works when you copy files from a USB device to 
the NSA. The same concept applies when you copy files from the NSA to a USB device.

Copying Files Example

Both storage devices contain file A. 

• A copy of files A and B from the USB device is transferred to the NSA. 
• File A from the USB device replaces file A on the NSA.

Synchronization makes the contents on the target device identical to the ones on the source device. 
You can synchronize files from a USB device to the NSA or from the NSA to a USB device. In 
addition, you may also synchronize files in both directions simultaneously.

Press and hold the COPY/SYNC button until you hear a beep to synchronize files. See 

 for details about configuring the synchronization settings.

When you synchronize files in one direction, contents on the source device replace the files on the 
target device.
