Its strength is its ability to play ISO files. The popular free app VLC cannot play ISO files. A little tip: deleting videos from within the app doesn't immediately affect the app's storage capacity. You can free up space by waiting a month or completely deleting them from the "Recently Deleted" section of the "Files" app. Alternatively, you can delete them from your iPad's settings under "General" -> "Storage" -> "Infuse" and they will immediately affect the storage capacity.
