Why can't I open my files in my downloa

[AC Question]

I want to open a couple of my music files on my downloader

There are a couple of possibilities. The files could be corrupted. They could be a file type you don't have an app for. They could be zip files, and you have to extract the music file from it (a zip file is like a suitcase - it's not a shirt, but you can put shirts in it; but you have to take them out to wear them).
