Find files hiding in a lot of sub directories

So I was moving a lot of my music to Amazon Cloud Drive, and ended with a lot of files still showing under a lot of sub directories. Problem was – how do I know which files are in what sub directory with out going into each of them.

Here is the answer:

K:\Music\dir /b /s /A-D /o:gn>list.txt

This captured all the files in the sub directories and saved them to list.txt

Hope this helps.
