Step 1. Install MovPilot Amazon Prime Video Downloader and Sign in
Helpful Tip:
If your hard drive has already been connected to your computer, you can just change the output folder to it and all the downloads from the downloader will be on your hard drive.
Tip:
But it doesn't recommend you to change the path for saving the newly-downloaded content because this change may easily cause some unexpected errors while running your computer or some apps.
