You can create a list of all files with the folders they are in in Windows fairly easily.

Open a command window (Start|run| then type "cmd" and press enter)

Change to the drive you want to list. So, if you want to see files on your external drive type E: (or whatever letter your drive is assigned to) then press enter.

Type the following command:

dir /s /b>FileList.txt

That will create a file called FileList.txt that will contain the folders and names of all files. The output is not all that pretty but it sounds like you are just interested in a list which this will give you.
