Few questions regarding subtitles

I have two questions:

1. What can I do with my "sub" folders ? Is there any way Jellyfin can look into these folders when processing metadata and such for each movie?
   
2. How does the Open Subtitles plugin work? Will it go though all my old content and try to download new subtitles for everything? (I would like to avoid this). Or will it process new content only, starting from the moment the plugin is installed?
   

Can anyone out there help me out ?
