  4. Use your computer's file browser to copy the update file from your computer to the Kindle root directory. (The root directory contains a number of folders — such as "audibles," "documents," and "music" — and is typically denoted by a "device" icon).
  5. Check your file browser's file transfer progress bar to ensure that file transfer to your Kindle is complete. When you're confident the file has transferred successfully, you can use your computer's unmount or eject function to safely disconnect Kindle from your computer.
