Yeah, I follow the naming a structure guidelines precisely, found at:
and the other ones for tv shows, music, etc.
I go to IMDB and copy the name with year in parentheses exactly, and paste it to rename my file. I have it within a folder called /Movies/Movie Name/Movie Name (year).ext. I split tv shows when they come as one file, and I merge movies when they come as multiple files. Honestly, Plex is great at finding metadata 99.9% of the time, at least with how I’ve tried to follow the naming conventions. It’s just tiny things that you probably would have to manually edit no matter what you do. (Like .hack//Roots shows up as .hack, which gets confused with the TV Show Hack.) I have not used FileBot at all, I’ll take a look at it, it would be nice to verify names and structures every so often for the files I may have minorly misnamed. I was more so just questioning the metadata process so I could 100% understand it, so I could better correct minor things like Studio Ghibli Collection, and .hack metadata.
