A messy share full of randomly named folders makes even a powerful NAS frustrating to use. This guide is for anyone who wants to organize media files for NAS storage in a way that stays tidy as the collection grows, works properly with media servers like Plex or Jellyfin, and makes backups and troubleshooting far less painful. It covers movies, TV shows, music, photos, home videos, and even security camera footage.

What you’ll need
- A NAS device with shared folders already created (or access to create them)
- A file manager or SMB/network connection to browse the NAS from your computer
- An external drive or portable SSD for staging and backing up files during the move
- A rough idea of what media categories you have: movies, TV, music, photos, documents, camera footage
Plan your folder structure first
Before you drag a single file across, decide on the top-level layout. This is the part that is hardest to change later, so it pays to get it right early.
- Create one top-level shared folder per media type, such as Movies, TV Shows, Music, Photos, and Home Videos, rather than mixing everything into a single “Media” dump.
- Inside Movies, create one subfolder per film. Inside TV Shows, create one subfolder per series, then a subfolder per season within that.
- Keep photos organised by year and event (for example a folder per year, with event-based subfolders inside), since date-based sorting rarely stays useful on its own once a collection grows large.
- Create a separate shared folder for anything that is not personal media, such as software installers or downloaded documents, so it does not get mixed in with things a media server will try to scan.
Choose a consistent naming convention
Consistency matters more than any particular style. A media server, and your own eyes six months from now, both benefit from predictable file names. If you plan to use a media server, take the time to look at Plex’s official naming guidelines, since getting this right the first time saves a lot of re-scanning later. This site also has a dedicated guide on naming files so Plex recognises them correctly if you use that platform specifically.
| Media type | Example folder | Example file name |
|---|---|---|
| Movie | Movies/Movie Title (Year) | Movie Title (Year).mkv |
| TV show | TV Shows/Show Name/Season 01 | Show Name – S01E01 – Episode Title.mkv |
| Music | Music/Artist/Album (Year) | 01 – Track Title.mp3 |
| Photos | Photos/2024/Beach Trip | 2024-01-15_beach-trip_001.jpg |
- Include the year for movies and albums to avoid confusing remakes, reboots, or re-releases with the originals.
- Use season and episode numbers with leading zeros (S01E01 rather than S1E1) so files sort correctly in any file browser.
- Avoid special characters such as colons, slashes, or question marks in file names, since some network file systems and older media players handle them poorly.
- Pick either spaces or hyphens as separators and stick with one style across the whole library.
Organise media by type
Once the structure and naming rules are set, work through each category systematically rather than moving files at random.
- Move movies first, since they are usually the simplest: one folder per title, one video file inside, plus subtitle files sharing the same base name.
- Move TV shows next, checking that each episode lands in the correct season subfolder and that specials or extras go in their own clearly labelled folder rather than mixed into a season.
- Sort music by artist and album, and consider a separate folder for compilations or soundtracks so they do not clutter individual artist folders.
- Batch-rename photos where possible using your operating system’s rename tools, then spot-check a sample of files afterwards to confirm the pattern applied correctly.
Handle security camera and smart home footage
If you record footage from home security cameras onto the NAS, such as clips from a Reolink CX410 or similar network camera, keep that footage in its own shared folder separate from personal media. Most cameras that support NAS recording will automatically create folders by camera name and date, which is a sensible default to keep. Set a retention rule or a manual clean-up schedule so old footage does not silently consume all your free space, and consider restricting access to that folder through the same configuring separate NAS user accounts and permissions approach you would use for any sensitive data.
Back up and transfer files safely
Large media libraries take time to move, and interruptions during a transfer can leave partial or corrupted files behind. A portable SSD, such as a Lexar Muse drive, works well as a staging area: copy files to the portable drive first, verify they play back correctly, then copy them across to the NAS in smaller batches rather than one enormous transfer. This also gives you a temporary backup if something goes wrong partway through. For an ongoing backup routine rather than a one-off move, it is worth setting up a proper scheduled backup, which this site covers in a guide on setting up NAS backup from a Windows PC.
Set up for media players and streaming devices
If a dedicated media player will read directly from the NAS, such as a Dune HD Homatics Box R 4K Plus connecting over the network, well-organised folders make browsing far easier even without a full media server running. Point the player at the top-level Movies, TV Shows, and Music folders as separate network shares, and it will generally display the same clean folder-per-title structure you built earlier. If you also run Plex or Jellyfin on the NAS itself, check the guide on setting up a Synology NAS from scratch for background on getting shared folders and services configured before you start scanning libraries.
Tips and troubleshooting
- If a media server is not picking up new files, double-check the folder is inside the library path it is actually scanning, not just somewhere nearby on the NAS.
- Avoid nesting folders too deeply. Three or four levels (media type, title, season) is usually enough; going deeper makes browsing slower on some devices.
- Rename files before copying them to the NAS where practical, since renaming across a network share is often slower than renaming locally first.
- Keep a short text file at the top of the library noting your naming rules, so the convention stays consistent even if someone else adds files later.
- Periodically check your NAS storage dashboard for free space, especially if security camera footage or 4K video is filling shares faster than expected.
Frequently asked questions
Do I need to rename files before copying them to the NAS?
Not strictly, but it is usually faster and easier to rename files while they are still on a local or portable drive, then copy the finished, correctly named files across to the NAS in one pass.
What happens if my naming convention does not match what my media server expects?
The media server may fail to match files to the correct title, show incorrect artwork, or leave items unrecognised entirely. This is one of the most common causes of a media server appearing to lose track of files it should be able to see.
Should photos and videos share the same folder structure?
They can, but many people find it clearer to keep photos and home videos in separate top-level folders, since photo management tools and media server apps often handle the two differently.
How much free space should I leave on a NAS used for media?
As a general rule, avoid letting any NAS volume fill much beyond 80 to 90 percent capacity, since performance can degrade and some background tasks, like snapshots or indexing, need working space to run properly.
