Question about .nfo files

[Zuczek1]

I have 20 TB HDD with movies on it, without folders. Just movies are located as .mkv files directly on HDD. I don't want to keep my metadata next to .mkv so default locations its ok, its on internal m2 drive to be precise. But what about .nfo? Should I enable it? What is difference vs not enable as for a normal user.
Thanks for reply!
Best regards

If you ever need to recreate a library, Jellyfin will pull info from the NFO files. So, for example, if Jellyfin originally misidentified some files and you manually corrected them, that accurate info gets saved in the NFOs. But if you recreate the library without those NFO files, Jellyfin will misidentify the movies all over again.
