Re-organising folders

[mdkb]

I am new to Jellyfin and am about to restructure my movies on a 4TB drive to suit the recommended approach. I just wanted to check if I will run into issues.

Shows will be fine, but with movies I currently keep them in folders by genre on the drive and would rather continue to do so (I dont only use this on Jellyfin and need to keep a visual order rather than just have everything in one folder). Example of my folders are:

/foreign
/action
/crime
/comedy

Then below each of those I have the actual movies in their own folders renamed as "/Movie name (year)"  following convention, and the movies themselves under those folders.

So, I believe I can do this by adding each of those folders (foreign, action, crime etc... ) to the Movie library in Jellyfin. Is this correct or have I misunderstood something?

Also - if it is correct - is there a limit to the number of folders we can add to a library, or does it impact anything by adding a lot of folders ?

(Note: they are all on the same 4TB external USB hard drive and not in seperate locations, and my OS is windows 10 x64)

Yes, you can have multiple folders in your library SETTINGS.  See my screenshot.

What you can't do is nest those folders in another folder and then point the library to that higher tier folder.
