| Note As of Windows Vista, these values have been replaced by KNOWNFOLDERID values. See that topic for a list of the new constants and their corresponding CSIDL values. For convenience, corresponding KNOWNFOLDERID values are also noted here for each CSIDL value.
The CSIDL system is supported under Windows Vista for compatibility reasons. However, new development should use KNOWNFOLDERID values rather than CSIDL values. CSIDL (constant special item ID list) values provide a unique system-independent way to identify special folders used frequently by applications, but which may not have the same name or location on any given system. For example, the system folder may be "C:\Windows" on one system and "C:\Winnt" on another. These constants are defined in Shlobj.h. |
