Fix NS_E_WMP_NO_DISK_SPACE (0XC00D1195) on Windows

Cause 1: The Drive You're Writing To Is Actually Full

The most common reason WMP throws NS_E_WMP_NO_DISK_SPACE (0XC00D1195) is that the destination drive has less than a few hundred megabytes free. WMP needs room for the file being written plus temporary buffers it creates mid-operation. It doesn't show a graceful "low space" warning — it just dies with this error mid-rip or mid-sync.

You'll hit this when ripping a CD to an external USB drive that's nearly full, or when syncing a large playlist to a portable player with almost no free space. The error appears right after the progress bar sits at 99% for a while — that's WMP writing the final chunks and running out of room.

Fix: Free up space or change the target

1. Open File Explorer, right-click the drive you're writing to, and check Free space. You want at least 1 GB free for a full CD rip, more for video files.
2. If it's low, delete old rips or move them elsewhere. Empty the Recycle Bin — that eats space silently.
3. If you can't free enough, change WMP's save location to a drive with room. In WMP, click Rip → Rip settings → More options. Under Rip music to this location, hit Change and pick a drive with space.

Pro tip: Check the actual free space on the system drive (usually C:) too. If that's full, WMP's temp operations fail even when your music drive has room. The fix is the same — clear temp files or expand the drive.

Cause 2: The Temp Folder Is Clogged or Redirected

WMP uses the %TEMP% folder for staging files during ripping, burning, and syncing. If that folder is on a nearly full drive — or got redirected by a cleanup tool to a small partition — you'll get 0XC00D1195 even when your music folder has plenty of space.

This sneaks up on people who use tools like CCleaner that "optimize" temp paths, or after a botched migration where the temp folder points to a leftover RAM disk or a tiny virtual drive.

Fix: Clear and verify the temp folder

1. Open the Run dialog (Win+R), type %TEMP%, press Enter. Delete everything inside that folder. Some files will be locked — skip them.
2. Check where the temp folder actually points. In System Properties → Advanced → Environment Variables, look at TEMP and TMP for the user. If they point anywhere other than C:\Users\YourName\AppData\Local\Temp, reset them.
3. If you changed them, restart WMP and try the operation again.

Why this works: The temp folder is where WMP writes partial data before moving it to the final destination. If that folder can't hold even a few hundred MB, the whole operation fails. Clearing it removes leftover junk and resets permissions.

Cause 3: Corrupted WMP Cache or Database

Less common but real: WMP's library database (a set of files in C:\Users\YourName\AppData\Local\Microsoft\Media Player) can get corrupted after a crash or a forced shutdown. When that happens, WMP's disk-space check goes haywire — it thinks the drive is full when it isn't. The error shows up inconsistently, sometimes working for one file, failing on the next.

Fix: Rebuild the WMP cache

1. Close WMP.
2. Open the folder above — %LOCALAPPDATA%\Microsoft\Media Player.
3. Delete the files wmdb, wmpfolders, and wmpdatabasetext. Don't delete the whole folder — just those three.
4. Launch WMP. It'll rebuild the library from scratch, which takes a minute or two.

Real-world trigger: I've seen this after a Windows update interrupted a library scan. WMP's database didn't close cleanly, and later every rip attempt failed with 0XC00D1195 despite 200 GB free. Deleting that wmdb file fixed it in under a minute.

Quick Reference

Start with the first fix — it resolves most cases. If you're still stuck after trying all three, check whether the drive is formatted as FAT32; files over 4 GB won't write there and WMP reports it as a disk-space error. Reformat to NTFS if that's the case.
