Change Windows special folders location programmatically

Question

How do I change the windows special folders location? (On Win7, Preferably using C#). Basically trying to do what the windows interface allows us to do, but programmatically. (See image) On top of changing the location it should also move any existing contents.

Searched around a bit, Apparently SHSetKnownFolderPath does not work with 32 bit apps (see the comments at the end)

Answer 1

You're looking to change registry entries. They should be at the following spots:

HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\User Shell Folders
HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\Shell Folders
