IDX Files Explained in Plain English. The .idx file extension is used by a lot of programs for different kinds of files. Here, we are discussing the IDX files that you find when downloading video. These IDX files are for subtitles. Some video subtitles use text. Others use graphics. So, if the video that you downloaded uses the graphics method, you will have a large .sub file containing the subtitle graphics, and a smaller .idx file.
