What is a .DUK file?
DUK files are video files saved in the Duck TrueMotion 1 format, which stores compressed video data using the TrueMotion codec developed by The Duck Corporation. The format was designed for multimedia applications and in-game cinematics during the 1990s, providing full-motion video playback on limited PC hardware. DUK files are commonly associated with older games and interactive media that used TrueMotion technology for video sequences.
You will likely only encounter DUK files if you are navigating legacy PC game files. File Viewer Plus can play DUK files and convert them to MP4 files, which many other devices and media players support.
