Newbie on WP51; how do I read what's on a disk? sm

I have a floppy with a resume copied onto it, among other things. How can I tell exactly what is on the disk?

Also, I've copied my PRD onto a different disk, and it shows the directory on there, but how can I see the entire PRD list (to make sure I"ve copied the right one; I think there are a couple loaded on my computer).

Thanks for the help. I'm dumb as dirt now but I promise I'll learn fast :)
