You can relocate your own folders easily.
If you want to move your stuff, check this out.

• Click your username at the top right of the Start menu to open your profile.
  
• Right-click Documents and choose Properties.
  
• Then click Location | Move and select the new location, or even create it at this time. You'll be asked if you want to move your documents;
  
• click Yes.
  

Don't try this with the Public folder, though: There's a Location tab, but no Move button.
