What is an IDX file?

An IDX file is a data file used by various DVD playback programs to display subtitles. It contains the subtitle text as well as cue points for when each subtitle should be shown during the movie timeline. IDX files are saved with a corresponding video file, such as an .AVI or .MKV file.

More Information

IDX files are similar to .SUB files, which are also used to store subtitles for videos. An IDX file is typically accompanied by a SUB file and the video file. They will also all bear the same filename.
