Hi, Kheldarson. Thanks for reaching out! I'm an Independent Advisor and a Microsoft user like you, and I am here to work with you on this issue.
Kheldarson, what is the extension of those files?
You can try to install K-Lite Mega Codec Pack, is a very powerful pack of codec, which allows you to run lots of files:

Please let me know if it works for you, ok? I hope this helps!:)
Kind regards,
