A video library player like the 'Films and TV' app on Windows 10

I’m looking for an app that lets me browse my video folder, which has different folders full of videos.

you can try Jellyfin

Plex is an option. It also allow you to acces your files remotely (like your private netflix)

So I can use it to open the folders within my video directory and watch videos? Just to make sure.

I assume in the library or in that tab is where the video files will appear? If so, I might indeed get it. Is it free or require an account?

Correct. You can also make collections and stuff if you’re into that (for example the whole MCU). The base version is free and very useable, paid version has some extras like skip intro for example.

I’m not familiar with the Films and TV app, but you might like this one, Kodi

Kodi or Plex should do the job.

Sadly, I tried it and found it too clunky. Maybe I’ll try it again. Thanks though.

Emby has now surpassed Plex in my opinion Better UI on TV and seems to not buffer as much as Plex in certain formats
