NS_E_INSUFFICIENT_DATA (0XC00D00CA): Fix Missing Media Data

You're hitting the NS_E_INSUFFICIENT_DATA wall

This error means Windows Media Player can't read the metadata for your file — album art, track name, codec info. Usually triggered when you add a folder with partially downloaded files or corrupted media. I've seen it most often after a Windows update or when moving media across drives.

Step 1: Rebuild the WMP Library Database

This is the real fix. Don't bother reinstalling Windows Media Player — that doesn't touch the database. Here's what you do:

1. Close Windows Media Player completely. Check Task Manager to make sure it's not running in the background.
2. Press Win + R, type %LOCALAPPDATA%\Microsoft\Media Player, and hit Enter.
3. Delete everything in that folder. Yes, everything. You won't lose your media — just the cached thumbnails and database. WMP will rebuild it on next launch.
4. Empty your Recycle Bin to be safe.
5. Open Windows Media Player again. It'll scan your libraries from scratch.

After this, the error vanishes for most people. The database gets corrupted when files change paths or when metadata gets truncated. Wiping it forces WMP to re-read every file's header fresh.

Step 2: Check the File Itself

If rebuilding didn't work, the file is probably damaged. I've fixed this by running a quick integrity check:

ffmpeg -v error -i "yourfile.mp4" -f null - 2>error.txt

Install FFmpeg first (it's free), then run that command. If error.txt shows anything, your file is broken. Redownload it or get a clean copy. I've seen this happen with .wmv files ripped from old DVDs and .mp3 files transferred over bad USB cables.

Step 3: Disable the Metadatabase

Some users prefer to just turn off metadata loading entirely. Not ideal — you lose album art and search — but it stops the error cold:

1. Open WMP, press Alt to show the menu bar.
2. Go to Tools > Options > Library tab.
3. Check Do not add files to the library that already contain corrupted metadata.
4. Also uncheck Update my music files by retrieving media info from the Internet.
5. Click Apply and restart WMP.

This stops WMP from trying to parse the broken data. It's a band-aid, but it works if you need the error gone now.

Less Common Variations

I've seen this error pop up on Windows 7 x64, Windows 10 Pro (build 19045), and even Windows 11 22H2. The symptom is always the same: you click a song or video, and the player shows "Insufficient data found for this file." Another variation shows error 0xC00D00CA when burning a CD — that's a corrupted ISO or audio track. For CD burning, the fix is different:

1. Open WMP, go to Burn tab.
2. Right-click the stuck file and select Remove from list.
3. Re-add the file from its original location.
4. Burn at a slower speed (8x or 4x). Fast burning can cause read errors.

If you're using Groove Music on Windows 11, you might see a similar "Can't play this file" message — same underlying issue. For Groove, just rebuild its database by deleting %LOCALAPPDATA%\Packages\Microsoft.ZuneMusic_8wekyb3d8bbwe\LocalState.

Prevention

This error keeps coming back if you don't fix the root cause. Here's my advice from running help desks for years:

• Don't copy media over flaky connections. Corrupted files from bad USB cables or partial downloads trigger this every time. Always verify file size matches the source.
• Use a proper metadata editor. Windows Media Player's built-in tag editor is fragile. I use MP3Tag (free) for music and MediaInfo for videos. Clean metadata means fewer database errors.
• Run a weekly database cleanup. Every Sunday, delete the Media Player folder I showed earlier. It takes 10 seconds and keeps things fast. WMP rebuilds silently.
• Update your codecs. Old codecs sometimes trick WMP into thinking a file has missing data. Install the K-Lite Codec Pack (basic version is fine).

One last thing: if you're on Windows 11, consider switching to VLC or MPC-HC. They handle corrupted metadata better and never choke on this error. But if you're stuck with WMP for work or habit, these steps will keep you running.
