What is an EXI file?
An EXI file is an index file created by YouTube for Android. It contains information used to play a video that has been downloaded for use offline. EXI files are not meant to be opened.
In some countries, such as India, the Philippines, and Indonesia, the YouTube app for Android allows users to save videos to play offline. The app downloads these videos as a series of .EXO chunks, each of which contains only a portion of the video.
When YouTube for Android saves a video as EXO files, the app also creates an accompanying EXI file. The EXI file contains information that YouTube for Android uses to play the video's EXO files in the correct order.
