I'm not being arrogant, I'm trying to give simple answers to simple questions.
If you have looked up what Kodi does as a HTPC application, then you know it can populate your video and music collections along with information and fanart given by external providers. This is what happens when you are 'scraping' your video and/or music collections into Kodi's internal databases. Scraping not only involves movie/music text information, but also fanart, backgrounds and artist thumbnails. Skins for Kodi can use different levels of additional info or getting extra fanart. It's up to you which skins suits your needs best. If you have no clue to what scraping in Kodi means, perhaps this wiki page will help.
When for whatever reason you are uncomfortable with external access/information, then scraping will probably be useless in your case. Playing videos or music in Kodi via the standard file browser is the only other option. As simple as that.
