I have been accumulating a lot of midi files for my Yamaha DKC850. At least
I *think* they are midi files, even though the file extension is ".FIL"?

 

Is there a way I can play them on my PC? Most of my midi folders on my PC do
not have an index of the songs and its not always easy to tell what the song
is just based on the filename.

 

It doesn't have to be "production quality" but good enough for me to create
a song title index, without copying each of them to a thumb drive and
tediously scrolling through each one on the DKC850?

 

Thanks

Jon
