NS_E_WMP_FILE_DOES_NOT_FIT_ON_CD fix (0XC00D10D8)

What's happening here

You're trying to burn an audio CD in Windows Media Player (WMP), and you get hit with error NS_E_WMP_FILE_DOES_NOT_FIT_ON_CD (0XC00D10D8). The message says: "The file is too large to fit on a disc."

This usually happens when you're trying to burn a music file that's longer than about 80 minutes (for a standard CD-R) or when the file's bitrate is too high for the disc format. But here's the thing—it's not just about file size in megabytes. WMP is checking the playback duration of the file, not the raw bytes. A single 90-minute MP3 file at 320 kbps will trigger this, because a standard audio CD holds only 74-80 minutes of audio.

Let's fix it. You can stop at any section once it works.

The 30-second fix: Shrink the file with WMP's built-in conversion

This works if the file is just a few minutes too long, or if it's a single long track like a podcast or live recording.

1. Open Windows Media Player (the old desktop version, not the UWP app).
2. Go to the Burn tab (top right).
3. Drag the problem file from your library to the burn list.
4. Look at the blue bar at the bottom of the burn list. It shows total time. If it's over 80 minutes, you'll see the error when you try to burn.
5. Right-click the file in the burn list. Choose Remove from List.
6. In your music library, right-click the original file (not in the burn list) and select Edit.
7. Click the Convert button on the toolbar (it looks like two arrows circling).
8. Choose Convert to Windows Media Audio (WMA). This shrinks the file size dramatically—sometimes 50% or more—without cutting duration. The quality dip is minimal for spoken word or low-fi music.
9. Wait for the conversion to finish. The new file will appear in your library with "(converted)" in the name.
10. Drag the converted file to the burn list. Check the time bar again. If it's now under 80 minutes, hit Start Burn.

Expected outcome: The burn should proceed without the error. If it still fails, the file is still too long. Move to the next fix.

The 5-minute fix: Split the file in half

If the file is a single track that's just too long (like a 90-minute DJ mix), you'll need to cut it into two parts. Use a free tool like Audacity or MP3DirectCut (I prefer MP3DirectCut because it doesn't re-encode—it just splits, which preserves quality).

1. Download and install MP3DirectCut (it's portable, no install needed).
2. Open MP3DirectCut. Drag your MP3 file into the window.
3. You'll see the waveform. Listen to find a natural split point—around the 40-minute mark if you want two equal halves.
4. Click at that point on the waveform. Then press Ctrl+B to set a cue point.
5. Go to File > Save Cue. Name it something like "Split Points.cue".
6. Now, go to File > Export Split Files. Choose a folder. MP3DirectCut will create two files: OriginalName_001.mp3 and OriginalName_002.mp3.
7. Close MP3DirectCut. Open Windows Media Player. Add both split files to the burn list. Check the time bar—each should be under 80 minutes.
8. Burn as usual.

Expected outcome: The burn works because each file is under the 80-minute limit. This is the most reliable fix for long single tracks.

The 15+ minute fix: Switch to a DVD or use a data disc

If you have a lot of files, or if you're determined to keep the original high-bitrate audio without splitting, just use a different disc type.

Option A: Burn to a DVD instead of a CD

Most modern DVD players and car stereos can play audio DVDs. A single-layer DVD holds 4.7 GB, which is enough for 100+ standard MP3s at 320 kbps.

1. Insert a blank DVD-R or DVD+R into your drive.
2. In Windows Media Player, click the Burn tab.
3. Click the small arrow under Burn Options (top right of the burn list).
4. Select Data CD or DVD. Not "Audio CD"—that's the default and it forces the 80-minute limit. Data disc mode stores files as-is, with no duration limit.
5. Drag your files to the burn list. You'll see a size bar (in MB, not minutes). As long as the total is under 4.7 GB, you're fine.
6. Click Start Burn.

Expected outcome: The disc will play in any device that supports MP3/DVD playback. Some older car stereos won't, so check your manual.

Option B: Use a CD-RW and burn as a data disc

If you must use a CD (not DVD), switch the burn mode to data disc. You'll lose the "audio CD" compatibility (won't play in CD players from the 90s), but modern computers and many Blu-ray players will read it fine.

1. Insert a blank CD-R or CD-RW.
2. In WMP, go to Burn Options > Data CD or DVD.
3. Add your files. The size bar shows MB. A standard CD-R holds 700 MB, which is roughly 4-5 hours of MP3 at 320 kbps.
4. Burn it.

Expected outcome: The disc works as a data storage device. If you need it to play in a standard audio CD player, this won't work—you'll need the splitting method from the previous section.

One last thing: Check your disc's actual capacity

Some CD-R discs are sold as 80-minute but actually hold only 74 minutes. If you're burning a file that's 75 minutes long, it'll fail. Check the printed label on the disc. If it says "74 min" or "650 MB," you're limited to shorter files. Buy 80-minute discs (700 MB) for the best chance.

Also, if you're using a CD-RW (rewritable), the capacity is sometimes lower—around 640 MB. Don't use CD-RW for audio CDs if you can avoid it; they're less compatible with players.

Real-world scenario: I had a user try to burn a 2-hour lecture podcast to a CD. The error popped up immediately. We split it into two 1-hour files using MP3DirectCut, burned both to separate CD-Rs, and it worked perfectly. The whole fix took about 4 minutes.

That's it. Start with the 30-second fix, then move down if needed. You'll have your disc burned in no time.
