basic troubleshooting:
- check if the movie has been mismatched as a different movie → sort your library by
Date Added
and check if there’s some odd movies you haven’t added; use>
Info
or...
>Get Info
to see if the missing file is associated with this item - check if the movie has been accidentally merged with another movie in your library → filter your library for
Duplicates
and check those items with multiple “versions” (same as above) - if you recently added lots of files or if there’s lots of duplicates you created on purpose… you can also use some 3rd party apps like ExportTools-NG to check if you can find the missing file
- double-check the naming of that file… Plex will ignore files named like an episode and won’t add them to a movie library
Last resort could be checking your server logs for some scan/match errors.
To ensure you get the full details in your logs it can make sense to clear that file and re-add it (Plex Dance).
