When Netflix downloads a movie or TV show to your device, the NFV file is saved to your device in a folder along with several other files, including the .MANIFEST, .NFS, .NFI, and .NFA files.

High-quality video will take longer to download and more space on your device, whereas standard quality takes less time to download and less space on your device. An hour of standard quality content is approximately 280 MB, and high-quality content is approximately 440 MB. To select your download video quality, tap the menu icon in the Netflix app then select "App Settings." Under the "Downloads" heading, select "Video Quality" and choose between "Standard" and "Higher" video quality.
