Windows 10: music file won't open

[Aliendope]

Under This Computer, click on Music files and automatically shuts down window. I am unable to open my music files. I can access iTunes directly, but all files (Audacity, etc) I've downloaded to my hard rive won't open. Did I delete some program or driver? Is it corrupted?

Try right clicking on a track and see if the Open With option shows up. Choose one of the options on offer. It may be the default programme to open music has fallen over.
