Netflix is well-known for streaming a wide variety of TV shows, films, comedy specials, documentaries, and original programming that isn’t always available on TV. Since December 2016, Netflix offline viewing has been an option through the mobile apps for Android and iOS. Data, including video, subtitle, and audio files must be kept on the user’s device in order to view Netflix offline. For storing the audio streams of downloaded content onto the device, Netflix created the NFA file.
Netflix had to discover a safe way to save the data for these videos on the user’s device in order to enable people to watch Netflix episodes and movies offline. In order to do this, Netflix created a collection of encrypted files that the Netflix app uses to access content when it is being viewed offline. One of these files, called NFA, is in charge of keeping the downloaded episodes’ or films’ audio information. NFA files, although have a different file extension, are essentially MPEG-2 Advanced Audio Coding (AAC) files. The other files required for the Netflix app to function without an internet connection are also kept in the same folder as the Netflix audio files. This covers NFS, NFV, and NFI files, among others.
