Here's another useful thing to do:
Install the Unofficial Appstore channel. Information is located here https://forums.plex.tv/topic/25523-unsupported-as-in-totally-unofficial-appstore/
Once installed you can use it to install other useful Apps and Channels.
The Channel I'd suggest installing right off the bat is FindUnmatched.
Right after installation you will need to go through the very minimal setup of the channel.
But once installed you can now use this App/Channel to walk through different libraries you have setup. It will identify any media you have on disk that is not showing up in a library.
This is probably the easiest way to identify problematic files or bad naming of media files.
Another really cool App that can be installed via the Unofficial Appstore is Plex2CSV which is also by the same person as FindUnmatched (dane22). This little app will allow you to create CSV files of each of your libraries. This is a great way to track offline the media you have.
