As you can see from the screenshot bellow, I have a lot of things on my Kodi. Too many. most of them come from kodi 14.x.
So i like to reset everything from time time, just like phones and computers, to keep things as much smoothly as possible.
Or when I’m just bored or fed-up with the current state of thing I simply drop the bomb.
So all you have to do is delete one single folder on your system:
For linux machines
First lets show hidden folders, by pressing ctrl+h
Delete the following folder
on Start menu type
Once you re-open Kodi it will repopulate everything and update itself back up. Brand new!
