A metadata manager can help organize a Jellyfin library by matching titles, writing local NFO files, and—if you choose—renaming media. tinyMediaManager supports that workflow, and its FAQ lists scraping, NFO read/write, and renaming among the free version’s base features. But incorrect matches still need review: the tool’s documentation supports the workflow, not a guarantee that years of mislabeled files will fix themselves.
What tinyMediaManager can do for a Jellyfin library
Jellyfin can identify media using its built-in metadata providers, but a separate manager can be useful when you also want to edit metadata locally or organize filenames and folders. tinyMediaManager describes itself as a media manager with metadata scraping, NFO creation, and automatic file and folder renaming, and it lists Jellyfin support on its official site.
Its FAQ says the free version includes base functionality such as updating data sources, scraping, reading and writing NFO files, renaming, editing, and exporting. Software tiers can change, so check the current FAQ for the features and operating-system support available to you.

Jellyfin can read local NFO files and gives local metadata priority over remote providers. As Jellyfin puts it, “Jellyfin can read and write local .nfo metadata files to import or export metadata from and to other programs and tools.” See its local NFO documentation.

- Entry-level NAS Personal Storage：UGREEN NAS DH2300 is your first and best NAS made easy. It is designed for beginners who want a simple, private way to store videos, photos and personal files, which is intuitive for users moving from cloud storage or external drives and move away from scattered date across devices. This entry-level NAS 2-bay perfect for personal entertainment, photo storage, and easy data backup (doesn't support Docker or virtual machines).
- Set Your Devices Free, Expand Your Digital World: This unified storage hub supports massive capacity up to 64TB.*Storage drives not included. Stop Deleting, Start Storing. You can store 22 million 3MB images, or 2 million 30MB songs, or 43K 1.5GB movies or 67 million 1MB documents! UGREEN NAS is a better way to free up storage across all your devices such as phones, computers, tablets and also does automatic backups across devices regardless of the operating system—Window, iOS, Android or macOS.
- The Smarter Long-term Way to Store: Unlike cloud storage with recurring monthly fees, a UGREEN NAS enclosure requires only a one-time purchase for long-term use. For example, you only need to pay $459.98 for a NAS, while for cloud storage, you need to pay $719.88 per year, $2,159.64 for 3 years, $3,599.40 for 5 years. You will save $6,738.82 over 10 years with UGREEN NAS! *NAS cost based on DH2300 + 12TB HDD; cloud cost based on 12TB plan (e.g. $59.99/month).
- Blazing Speed, Minimal Power: Equipped with a high-performance processor, 1GbE port, and 4GB RAM on Board, this NAS handles multiple tasks with ease. File transfers reach up to 125MB/s—a 1GB file takes only 8 seconds. Don't let slow clouds hold you back; they often need over 100 seconds for the same task. The difference is clear.
- Let AI Better Organize Your Memories: UGREEN NAS uses AI to tag faces, locations, texts, and objects—so you can effortlessly find any photo by searching for who or what's in it in seconds. It also automatically finds and deletes similar or duplicate photo, backs up live photos and allows you to share them with your friends or family with just one tap. Everything stays effortlessly organized, powered by intelligent tagging and recognition.
Choose the workflow that matches the problem
| Approach | Best fit | What to consider |
|---|---|---|
| Jellyfin’s metadata providers | Correcting metadata while keeping the workflow inside Jellyfin. | Jellyfin documents built-in providers including TMDb and OMDb, with additional providers available through its plugin catalog. See Jellyfin metadata documentation. |
| External manager writing local NFO files | Managing metadata outside Jellyfin or keeping metadata alongside the media for reuse. | Review matches before writing changes; local metadata can take priority over remote provider results. |
| External manager with renaming | Cleaning up inconsistent filenames and supported sidecar files as well as metadata. | Inspect the renaming pattern and scope before applying it. tinyMediaManager’s movie renamer operates within its configured data source. |
Set up a cautious metadata cleanup
- Add the media folders. In tinyMediaManager, add the folders containing the relevant movies or shows as data sources, then let it identify the titles using its available metadata sources. The product site lists sources including TMDb and TVDB.
- Review uncertain matches. Do not apply changes blindly to titles that could match more than one release. Jellyfin notes that provider identifiers can improve identification and can be included in a movie or show filename or folder name. Its provider identifier guide explains the supported approach.
- Check the renaming pattern and scope. If you intend to rename files, inspect the proposed pattern and the selected data source first. The tinyMediaManager movie renamer documentation says it can rename supported video files and related NFO or artwork files according to its settings, and that it works only inside its own data source. For shows, consult the tool’s TV-show NFO format documentation.
- Write local NFO metadata. Have the manager write the metadata files you want Jellyfin to use. Since Jellyfin prioritizes local metadata over remote providers, an incorrect NFO can preserve an incorrect result rather than fix it.
- Refresh the Jellyfin library. Scan or refresh the relevant library so Jellyfin can read the updated files. Check the resulting titles and details instead of assuming every mismatch will be corrected automatically.
Why a match may remain wrong
A scraper can only use the information it can associate with a file. Ambiguous titles, unusual releases, and inconsistent naming can lead to a wrong match; the external manager does not remove the need to confirm those cases. Adding a provider identifier to a filename or folder can help Jellyfin distinguish the intended item, but it is a correction to the identification input—not a blanket fix for every metadata problem.
Also distinguish metadata cleanup from file renaming. Writing an NFO changes the local metadata Jellyfin reads; renaming changes names and may affect associated sidecars. If your priority is simply to correct a title, you may not need to rename anything. If you do rename, make sure the manager is pointed at the intended data source and that the pattern produces the layout you want.

When to use Jellyfin alone
Try Jellyfin’s own providers first if the filenames are already organized and you only need to adjust metadata. An external manager is more useful when you want to batch-edit outside the server, preserve metadata in local NFO files, or rename media in addition to scraping. Jellyfin’s guidance for movie files and folders can also help you check whether the library’s organization is compatible with its identification process.
A community member’s question about finding a free program to batch-rename media illustrates the practical need, but it does not establish how widespread the problem is or how reliably any tool resolves it. See the discussion on r/jellyfin.
