Connect the NOOK to your computer with the included USB cable. NOOK will then show where hard drives and other USB drives show (under My Computer on Windows or on the desktop on Mac). Double-click on the NOOK drive to open it.
In another window, open the folder where you stored the eBook files on your computer (we recommend downloading and storing them on the desktop or in My Documents in a folder called 'eBooks'). You can then drag and drop the eBook file(s) from your computer to the "my documents" folder or to the root of the NOOK.
After the files are finished transferring to the NOOK and BEFORE unplugging the USB cable, you must eject the device from the computer. Removing the USB cable before doing this can cause harm to your eBooks and/or the NOOK. Simply right-click on the NOOK drive and select the undock, eject, or unmount option.
