how to add files to http

hi, I threw the video files to the folder-/home/osmc/Movies-on the flash drive where the os is installed. Also inserted a flash drive on which there is also a video. Why when I go over http there are no video files displayed and they are not looking for? Where to throw files on a flash drive with the OS to find them?
How to create a playlist and add your own videos to it, I create a playlist but I don’t see how to add a video to it.

Well the Web interfaces has two sections. In the Movie/TV Show section you will only find items that you have added to your library other files/movies like the USB stick you find via Browse - Files menu.
