^^^^^ That. Is not the path that the link below is talking about, though. It actually does; it is rather confusing though. :/ I agree with the below. But I have never seen a version of Windows on which c:\ProgramData was the actual path for FOLDERIDProgramData. Can you reference documentation that states that it was there, for some version? This documentation speaks of: c:\Documents and Settings\AllUsers\Application Data (which I knew from XP, and I think 2000, not sure I remember NT) In Vista.0, Vista.1, and Vista.2, I guess it is moved to C:\users\AllUsers\AppData\Roaming (typically). Neither of those would result in C:\ProgramData\Python.

The SO answer links to the KNOWNFOLDERID docs; the relevant entry specifically is at

http://msdn.microsoft.com/en-us/library/windows/desktop/dd378457.aspx#FOLDERID_ProgramData

which gives the default path as,

%ALLUSERSPROFILE% (%ProgramData%, %SystemDrive%\ProgramData)

checking on my local windows 7 install gives:

C:>echo %ALLUSERSPROFILE% C:\ProgramData

C:>echo %ProgramData% C:\ProgramData

It's referring to KNOWNFOLDERID constant FOLDERIDProgramData. The actual on disk location for this has changed over windows versions. As noted below in the SO link given:

"Note that this documentation refers to the typical path as per older versions of Windows. In modern versions of Windows it is located in %SystemDrive%\ProgramData."
