Redownloading the Corrupted Files

If the 0xc10100bf error code only appears when you open files that you previously downloaded from the internet, file corruption may be to blame. The majority of the time, this issue will arise after an interrupted download or after an overly cautious antivirus software forced the operation to end before the download was finished.

If the situation described here applies, you should be able to resolve this issue by retrying the operation and making sure that no external interference could cause it to end prematurely. If you’re using an antivirus programme from a third party, go ahead and turn off real-time protection before the process is finished. You can do this by right-clicking the AV icon in the tray bar of the majority of security suites.

Using VLC Media Player

The only workable option at this time is to use a third-party alternative if you’ve tried every possible fix above and you’re still getting the 0xc10100BF (This file isn’t playable) error when using Windows Media Player or the Movies & TV app.

VLC is by far the most adaptable free third-party video player. This tool may still be able to play videos even if the video corruption is the cause of the playback failure. To avoid the 0xc10100BF error code and install and use the most recent version of VLC Media Player, follow the instructions listed below.

Final Words

You attempted to use Windows Media Player to play an MP4 file that you had downloaded or copied to your computer from an external source but nothing happened. Instead, a message with the error code 0XC10100BF was presented to you. You attempted to use the Movies & TV application instead, thinking that perhaps that was an occasional glitch, but ran into the same issue.
