I haven't use old plugins and I'm not sure about that. However, the plugin I used needs to be placed in the new folder and it wouldn't work if be placed in the old directory.

I think we should leave the folder contents as is to avoid any impact to users. The plugin structure seems different between these two plugin systems. Ref. https://github.com/yt-dlp/yt-dlp/blob/master/yt_dlp/plugins.py#L138-L171

Okay, I see. Isn't yt_dlp_plugins the new folder name though? Your PR has yt-dlp-plugins instead (with hyphens not underscores).

[silver886]

It is hyphen. We need to use the one with get_executable_path to setup as portable plugin folder. Ref. https://github.com/yt-dlp/yt-dlp/blob/master/yt_dlp/plugins.py#L69-L80

I'm having this issue and can only manually create the yt-dlp-plugins directory now. Hopefully this PR will be merged soon.
