Plex organises everything you watch and listen to into libraries, and getting this right makes a real difference to how enjoyable your server is to use. This guide walks you through how to create and manage multiple Plex libraries, whether you want separate collections for movies, TV shows, music, photos and home videos, or just want to tidy up a server that has grown messy over time.

What you’ll need

  • A working Plex Media Server, installed on a computer or NAS device
  • Access to the Plex Web App with admin rights to that server
  • Your media files organised into folders on a drive the server can reach
  • Files named in a way Plex can recognise (this matters more than most people expect)

If you haven’t sorted your files yet, it’s worth reading up on naming your files correctly for Plex before you start, since a library is only as useful as the metadata it can find for your content.

Why use multiple libraries

A single Plex server can hold several libraries side by side, each dedicated to one type of media. Instead of dumping movies, TV shows, home videos and music into one messy pile, you split them by type and even by purpose, for example a separate library for kids’ content or a home videos collection kept apart from your main movie library. Each library gets its own scanner and agent settings, its own metadata language, and its own visibility in search, so keeping things separated genuinely improves how Plex organises and displays your content.

Creating a new library

  1. Open the Plex Web App and click the settings icon (the wrench) to open the settings menu.
  2. Check that the correct Plex Media Server is selected at the top of the settings menu, especially if you manage more than one server.
  3. Select Libraries under the Manage section of the menu.
  4. Click Add Library to start the setup process.
  5. Choose the type of library you want to create: Movies, TV Shows, Music, Photos, or Other Videos.
  6. Give the library a clear name and choose the language Plex should use when pulling in information such as plot summaries from the internet, then move to the next step.
  7. Add the folder or folders where that media is stored. Use the browse option to locate the correct folder rather than typing the path from memory, to avoid mistakes.
  8. Add every folder that belongs to this library. If you have media split across multiple drives or locations, you can add several folders to the one library and Plex will combine the content automatically.
  9. Once all the source folders are added, confirm and create the library. Plex will begin scanning the folders straight away.

One important rule: never point a library at the root of a drive, such as an entire drive letter on its own. Create a proper subfolder for your media, like a dedicated Movies or TV Shows folder, and point the library there instead. Using a root drive as a library location tends to cause scanning problems and odd behaviour down the track.

If you’re setting this up for the first time and want a deeper walkthrough specifically for movies, the guide on adding and organising movies in your Plex library covers that process in more detail.

Adjusting advanced settings

Most people never need to touch the advanced options when creating a library, but they’re there if you want more control. These settings appear after you’ve chosen a library type and added your folders.

  • Scanner: analyses the folder structure and file names to work out what each item is. Plex picks a sensible default, but you can change it if your content needs a different approach.
  • Agent: takes what the scanner finds and searches local and online sources for matching metadata like artwork, cast details and descriptions. Again, a default is chosen automatically and usually works well.
  • Visibility: controls whether this library’s content appears in global search results across your server, or only when you’re browsing that specific library.

If your TV library uses season and episode numbering from a source like TheTVDB rather than the default database, there’s a specific episode ordering setting worth checking so episodes match up correctly.

Managing existing libraries

Once you have several libraries running, managing them is mostly about keeping folders tidy and letting Plex do its scanning. From the Libraries section in settings, you can edit a library at any time to add or remove folders, rename it, or change its scanner and agent. If you add a brand new library to a server that clients are already connected to, you may need to restart the client app on your TV, phone or streaming device before the new library shows up there.

After adding fresh content to an existing library, Plex usually picks it up automatically, but if it doesn’t appear you can trigger a manual scan. There’s a full explainer on how to refresh your library after adding new content if you run into that situation. For anyone running Plex on network storage, the guide on setting up Plex on a Synology NAS is a useful companion piece, since library management works the same way regardless of where the server itself lives.

Tips and troubleshooting

  • Keep each library type separate. Mixing movies and TV shows in one library confuses the metadata agents and leads to incorrect matches.
  • Use clear, consistent folder names, since scanners rely on folder structure as much as file names to identify content correctly.
  • If new episodes or movies aren’t appearing, check that the folder is actually included in the library’s source list before assuming something is broken.
  • Restart client apps after adding a new library if it doesn’t appear on a TV or mobile device straight away.
  • Avoid pointing libraries at a drive’s root folder. Always use a dedicated subfolder to prevent scanning issues.
  • If metadata looks wrong, try switching the agent for that library rather than assuming the content itself is at fault.

Frequently asked questions

How many libraries can I create in Plex?

There’s no strict limit enforced for typical home use, so you can create as many libraries as you need for movies, TV shows, music, photos and other video content. Most people find a handful of well organised libraries far more useful than dozens of overlapping small ones.

Can I combine multiple folders into one library?

Yes. When adding or editing a library, you can add several folders as sources, and Plex will treat their contents as one combined library rather than keeping them separate.

Why isn’t my new library showing up on other devices?

This is usually a client caching issue. Restarting the Plex app on the affected TV, phone or streaming box typically forces it to reload the current list of libraries from the server.

Should I use separate libraries for kids’ content?

Many households do exactly this, creating a dedicated library for children’s movies or shows so it can be filtered or hidden separately from general content, particularly useful if you also use shared access for friends or family and want to manage what each person sees.
