Is there a way to prevent file joining?

Run a test with one of the files Plex has combined. Remove the metadata from one of the files, then put it back in the library. See if Plex still combines them.

  1. In the Video library with the combined files, move your mouse over the poster/cover art for one of the combined files. Click on the pencil in the lower left corner. This brings up the edit window for the file(s).

  2. Choose Info on the left side. You should see the list of combined files, including path to their location.

  3. Move one of the files outside of the library, where it cannot be seen by Plex scanners.

  4. Perform Steps 2 - 4 of the Plex Dance: Scan the library; empty trash; clean bundles.

  5. Make a backup copy of the file you removed from the library.

  6. Remove all embedded metadata from the MP4 file. Right click on the file, choose Properties -> Details tab. Choose “Remove Properties…” In the “Remove Properties” window, choose “Remove the following…”, click Select All, then OK. When it returns to the Details tab, the Title, Descriptions, etc fields should all be empty.

  7. Move the file back to the Library. Perform a manual scan if the system does not auto-scan.

Did Plex combine the file like before or keep it separate?
