Windows 7: Profile Folders Missing

Hi there,

Some of my folders are missing from my user folder, those being Music, Documents, Downloads and Videos. Unfortunately I mapped these folders to other locations and then removed the drive, so when I booted up again the icons had just vanished.

Now I have the folders stored on a server and would like to remap them. I have mapped Music, Documents and Videos via the start menu and right clicking on the items under my username. This hasn't re-established the icons but they are now mapped.

So my question is, how would I restore the original icons so I can map them again? Or are they simply folders? It's hard to tell with this feature tbh, folders/shortcuts/some other link?

Also what the hell is the difference between Libraries and profile folders? Surely only one is needed?

Nick.
