There is the Environment.SpecialFolder enum.

The comprehensive document on the subject is the "Windows User Experience", which used to be published as a book, but can now be found online in many places (such as http://www.scribd.com/doc/36857902/Windows-User-Experience)

Windows File System Namespace Usage Guidelines: http://www.microsoft.com/downloads/details.aspx?FamilyID=88AD7E7C-4068-48B8-9503-E160A6693BBA&displaylang=en

Most of the document is specific to Windows Vista. The last section, titled "Accessing Well Known Folder Locations," discusses the SHGetFolderPath (Windows XP and earlier) and SHGetKnownFolderPath (Windows Vista) functions, which are what the .NET Environment.GetFolderPath method relies upon.

The Environment.SpecialFolder enumeration has been greatly expanded in .NET 4.0. It includes a lot more values than the 3.5 version did.
