Use CD.. to move one level up in folder structure.
Use CD <folder name> to go to lower level folder.

When you are at the correct drive, use DIR to list files
and folders. Use DIR/S to list files and files in lower
folders.
Use DIR/S > Myfilelist.txt to create a text file with all
the file names.
When you finish you can click to close the window.
Some folks still use DOS.
