How to Fix 0xC10100BF (This File Isn’t Playable)

The error code 0xc10100BF (This file isn’t playable) occurs for some Windows 10 users when they attempt to play MP4 files on the computer using the Movies & TV app or Windows Media Player.

0xc10100BF Error Code – The File Isn’t Playable

If you’re determined to get to the root cause of this issue, you should start by deploying the integrated troubleshooting utilities that might fix this problem automatically (Windows Media Player Troubleshooter and Video Playback Troubleshooter).

In case you already did this with no success, the next logical step is to try and reinstall or reset the problematic application. In case you’re dealing with a corrupted Windows Media Player or Movies & TV app instance, this operation should fix the problem entirely.

However, in case the only time you’re seeing this error code is when trying to open files that you previously downloaded over the Internet, ensure that the download was not interrupted before it’s completion. It’s also possible that an overprotective AV interference stopped the data exchange before the operation was complete.

Also, if you’re attempting to play the .mp4 files that are triggering the error from a flash drive, test to see if you’re not actually dealing with bad sectors by re-downloading the files on your HDD or SSD.

And finally, if you didn’t try this already, install and use a 3rd party equivalent video playback tool like VLC and see if the videos are playing without issues. VLC in particular is capable of playing partially corrupted files when other equivalents fail.

Method 3: Redownloading the Corrupted Files

In case you’re only encountering this problem with files that you previously downloaded online, file corruption might be the catalyst that’s throwing the 0xc10100bf error code. In most cases, this problem will occur after an incomplete download or after an overprotective antivirus suite ended up terminating the operation before the download was complete.

If this scenario is applicable, you should be able to fix this problem by retrying the operation and ensuring that no interference can cause it to interrupt prematurely.

In case you’re using a 3rd party antivirus, go ahead and disable the real-time protection before the operation is complete. With most security suites, you can do this by right-clicking the tray bar icon of your AV.

Disable Antivirus

Note: Some affected users have reported that in their cases, it helped to download the files onto an external hard drive first and opening them from there.

If this method is not applicable or you already tried this with no success, move down to the next potential fix below.

Method 4: Using a Different USB (if applicable)

If you’re only encountering this issue only when attempting to play .MP4 files from a flash USB disc, chances are you might be dealing with a bad device – Especially if you already tried to format the drive once before and the end result is the same.

In case this scenario is applicable, chances are your USB drive contains bad sectors that cannot be fixed, so any formating attend will not prove to be effective.

In this case, try using a different USB drive or store the files directly on an HDD/ SSD and see if you still end up encountering the same 0xc10100BF error code.

If you are willing to consider using a 3rd party alternative, move down to the next potential fix below.
