This is the
CLSID List and Windows Special Folders Cheat Sheet. Most of the Special Folders within the Operating System are known by unique strings also known as CLSIDs or Class Identifiers. Some can be used with FileSelectFile, FileSelectFolder, and Run. If and when a Windows Shell needs an access to a system folder, it uses the CLSID to search through the Registry to search for the appropriate .dll or other object.
