Clearing cache on firestick

Since I Expand external storage on fire stick with a USB how do you clear your cache . I used to have cache on when I watched movies from sites and now since I moved it I don’t see any cache after using it

@Dianond

You would have to go to managed applications I and you will see your apps there click on one and clear cache.

That’s for kodi but all your apps should show. Do the same for all your apps.
