Inspect the underlying item before changing it
Ask the authorised library operator to inspect the file associated with the visible entry and its episode naming. Keep the source file and the metadata listing together in the investigation. Do not delete a valid double-length item because the client displays fewer cards than the programme’s episode list.
For an illustrative series, one file contains the first and second episodes, followed by a separate file for episode three. The library can legitimately show two entries for those three programme episodes. That observation does not by itself indicate that the second part is absent from the stored media.
Use the documented multi-episode model
Jellyfin’s TV-show guide gives the S01E01-E02 naming pattern and says a file containing several episodes appears as a single entry with metadata from those episodes. Use the library’s real season and episode identities; an invented range does not change what a file actually contains.
Check the intended series and source organisation before renaming. Keep a private record of the original name and the proposed correction. A correct filename can improve identification, but it does not split the video into independent files or prove that an external metadata provider uses the same edition and numbering.
Choose whether separate files are actually needed
The official guide recommends splitting into individual episodes where appropriate. That is an operator decision involving the authorised source, suitable tooling and a retained original. Merely duplicating the same double-episode file under two names would create two references to the same complete content rather than separate episodes.
If separate navigation is important, plan and validate the resulting media carefully. Confirm the opening and ending of each part, required audio and subtitle tracks, and correspondence with the intended episode numbers. This article does not supply editing commands or claim that an arbitrary split preserves every track correctly.
Verify the viewing outcome rather than the card count alone
After any agreed correction or split, refresh the relevant library through the supported workflow and inspect the resulting entries. Play a short permitted passage from each expected part. A desired number of posters alone is not proof that each card now points to the right segment.
Keep the decision explicit: retain a correctly identified combined entry, or create and validate separate episode files. Report the chosen source model, naming, displayed metadata and playback result to the operator. This is a Jellyfin-specific library interpretation, distinct from an XMLTV numbering offset or a missing live programme-guide entry.
Questions about this guide
Does one entry always represent exactly one episode file segment?
No. Jellyfin documents a single entry for a file containing multiple episodes.
Does renaming a combined file split its video content?
No. Naming and physically separating media are different operations.
