Plex Not Showing New Movies? Make It Look Again
You copied a film into your movies folder. You open Plex. It isn't there.
Nothing is broken. Plex only knows about the files it has looked at, and it doesn't watch your folders every second — especially when the folder lives on a NAS, a network share, or inside Docker, where the signal that says "a new file arrived" often never reaches it.
The fix is to tell Plex to look again. On a server, the usual advice is to SSH in and run a command with a library number you have to find first. Here is the version without any of that.
The one-click fix
Commandeck ships a free button pack for Plex. Install it once and you get a button that tells Plex to go through every library again — your films, your series, your music — and names each one as it goes.
- Open Commandeck and add your server as a machine (its address, your user name, your password or SSH key).
- Menu ☰ → Button Packs → Linux → Plex (Docker) → Install, and pick that machine. (Plex installed straight on the machine rather than in a container? Take Plex (system install) instead - same buttons, different commands underneath.)
- Click Look for new films and episodes.
Films... looked through.
Series... looked through.
Music... looked through.
Plex reads the new files in the background; they appear as it goes.
Nothing to type, no library number to look up. The new film shows up in Plex a few seconds later — a big library takes a few minutes.
If it still doesn't appear
Three reasons account for almost every case, and the same pack answers all three.
The disk is full. Plex needs room to write what it learns about a file. When the drive is at 100%, a scan can finish without adding anything — and in the worst case it damages Plex's catalogue. Click Space & conversion cache: it reads every folder Plex can see and warns you in plain words if one is nearly full.
Plex cannot read the file. A film copied from another machine often keeps that machine's permissions. Click What Plex reported — if Plex could not open something, it says so there, once, instead of buried in thousands of lines of its own housekeeping.
The catalogue itself is damaged. Rare, but it explains a Plex that forgets films or loses watched marks. Click Is the database healthy? — it checks a copy of Plex's database, so it changes nothing, and tells you what it found.
The rest of the pack
The pack is free and has fifteen buttons. The ones people click most:
| Button | Answers |
|---|---|
| Is Plex running? | Is it up, and if it stopped, why |
| Why is Plex busy? | Converting a video, scanning a library, or neither |
| What Plex reported | Every message Plex wrote, each one once, with how many times it repeated |
| Why is the graphics chip not used? | The four reasons Plex converts video the slow way |
| Restart Plex | The first move when something is stuck |
| Clear the conversion cache | Deletes temporary converted video only — never your films |
Every command is visible before you install, and you can edit any of them afterwards.
Running on your server means SSH
Your Plex server is a different machine from the computer you're sitting at, so these buttons reach it over SSH. That part is Commandeck Pro — $29 once, for good, with a 14-day trial that asks for no card and no account. The pack itself, like every pack, is free.
Nothing leaves your computer: no account, no cloud, no server of ours in the middle. Your machines and passwords stay on your device.
