I know there was this 4-year old thread: https://forum.videolan.org/viewtopic.php?t=125327 But there seems to be no resolution for the problem STILL.
I'll just try to clearly state my question:
"How do I make VLC player play next file in the folder without creating a playlist/use "open folder..."/use "open multiple files..."/other long workarounds."
Ideally, I want it to be like in MediaPlayerClassic: you double-click a video in certain folder, watch the video and it automatically opens the next video in that same folder. Simple as that. Is it doable?
