A PLS (Playlist) file is a multimedia playlist file format used by various media players. It's a plain text file that contains a list of audio or video file locations, along with optional metadata such as track titles and lengths. The PLS format is relatively simple and widely supported, making it a common choice for creating and sharing playlists. The file typically contains entries with the file path or URL of each media file, allowing the media player to quickly locate and play the listed files in sequence. PLS files are often used for internet radio streams, allowing users to easily access and listen to online broadcasts. The format is human-readable, making it easy to edit and customize playlists manually. While more advanced playlist formats exist, PLS remains a popular option due to its simplicity and broad compatibility.
