Filename Backup

Hello

I am looking for a way to create a text-based backup of all files on my external drives. I have a "large" collection of songs, movies and other stuff which I can happily live without, hence I don't have a backup for them. I would, however, like to keep track of all the files I have in case of a hard drive failure - that is folder structure and file names. Is there any way to do this? I also connect a Windows computer to it so I guess that increases the possibilites.

Thanks.
