Multiple redundant folders for media

[rocks911]

I fear I've made a complete mess of things in trying to get this W7 to share media with my devices.

When I click on Start/Computer the left pane shows among other things Network and below that the name of my computer and that breaks out into a bunch of redundant folders. There is no opportunity to delete these folders.

I've included a screen grab. What is this all about?

I think this has to do with user accounts, or at least users (if they are different topics) because when I was trying to set up a media player I spent days trying to get it to work following many peoples advice. Unfortunately I think that over the course of that time I created different accounts and I think thats why I have so many shortcuts.
When I surf my Network through my Boxee Box media player I go to Samba/Rocks911(computer name)/Users/and there are a few users.
The usual Public, Guest, Default, Default User, All Users, and D's, and DS.
D's is the user that Boxee recognizes and uses to access my files, but DS is apparently something I created that didnt work out for me.
How do I find a complete list of accounts/users? I think this has to do with why I have so many folders. By the way, all the folders work.
