"Table of Contents" for flashdrives

Hello,
Is there a way to create a "table of contents" for the folders (and then files within the folders) that are on my flash drive? I am looking for a way to know what is on each flash drive. I do not need the actual entire file copied, just the names of the folder and the names of the files within the folders so I can create some sort of master list or table of contents for each flashdrive I have.

Thanks!
