Amazon released the Kindle 2 e-reader with an e-Ink display that prevents eyestrain while reading books on the device. The Kindle 2 has about 1.4 GB of space available for you to upload books, documents and audio files either wirelessly or through the USB cable that comes with the device. You can use the USB cable if you need to transfer books from your PC to the Kindle 2. This helps if you are not in range of a wireless or 3G network.
Plug the smaller end of the USB cable that came with the Kindle 2 into the designated port on the device. Plug the larger end of the cable into an open USB port on your PC. You can only use the cable that came with the device to transfer books; other USB cables will not fit into the Kindle 2's micro-USB port. You do not need to use a powered USB port for transferring books.
Double-click the Kindle 2 removable drive icon on your PC's desktop. If the icon does not appear, locate the Kindle 2 folder in "My Computer." While plugged into a PC, the Kindle operates only as a removable drive; you cannot read books while transferring files. The USB cable simultaneously charges the Kindle 2.
Drag your book files to the Kindle 2 "Books" folder or Kindle 2 icon and drop them inside. The book files will only transfer if you add them to a folder that supports the e-book formats. Eject the Kindle 2 from the PC before unplugging the USB cable.
