Few questions regarding subtitles

[Cognicom]

I have a few libraries that were previously being used with Plex, using a plugin called Subzero which would download subtitles automatically and save them under a folder called "sub" (inside each movie folder).
Example:

• \docs\james bond behind the scenes\james-bond-bts.mkv
  
• \docs\james bond behind the scenes\sub\james-bond-bts.en.srt
  

Plex would play the video and the subtitle fine.

Now that I'm on Jellyfin, I was wondering how I should deal with this situation. Naturally, Jellyfin completely ignores the "sub" folder. And because of this a lot of my content doesn't play with subtitles at the moment.
I also have titles where the subtitles (srt) simply exist side-by-side with the video file. In these cases, subtitles appear fine.

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?
   

1. Jellyfin expects the subtitles to be in the same folder as the video file, so in the above example, moving james-bond-bts.en.srt into \docs\james bond behind the scenes\ will make the subtitles visible to Jellyfin. Consult this reference: https://jellyfin.org/docs/general/server...nal-files/. Note that you'll need to do a library re-scan to get the server to notice them.
    
   
2. Sorry, can't help you with that; I've never used it - but hopefully someone else will be able to help.
