Clearing a folder "streaming-playlist"

Hi, everybody
I began to greatly increase the folder « streaming-playlist » tell me how you can reduce it. What is in this folder?

This folder contains the videos in HLS format.

There were a few questions:

  1. I have both options enabled now « WebTorrent » and « NLC with P2P » if I disable P2P the folder is cleared?

  2. What can be the consequences if these parameters are changed in the course of work?

Changing this settings will only affect future videos. It does not clean existing videos.

How can I clear an existing one? How can I understand which video was uploaded using which technology?
