Preserve the actual mismatch
Record the file’s title and year, folder name, assigned library type and the film Emby currently displays. Keep these facts before changing artwork. A poster can be replaced cosmetically without resolving the underlying identity that supplies descriptions and other metadata.
Use a hypothetical pair such as Harbour Lights from one year and a later film sharing the same name. Write the intended year beside the actual file, rather than assuming the system can infer a remake from its codec or resolution. This example is invented to show the identification problem.
Use a small naming correction
Consult the current naming guide for the supported title/year structure and optional identity tags. Back up relevant files and metadata before a larger library reorganisation. Test one known item first rather than renaming hundreds of films based on an unverified pattern.
Check the result in the normal library view and the folder-oriented view where useful. Emby’s documentation explains that default library views are metadata-based, so the folder hierarchy and the displayed catalogue do not have to appear identical. Keep that distinction when comparing screenshots.
Check the item beyond the poster
After correcting identification through the supported route, verify the title, year, description and intended media file. Inspect alternate versions or extras if present so they remain associated with the correct work. A successful metadata match still does not establish that every version plays on every client.
If asking for help, provide a redacted path, library type, intended identity and displayed identity. Do not upload the film or a private server password. This focused record helps support investigate naming and matching instead of chasing unrelated Wi-Fi settings or a subscription sign-in that already works.
