Is there a definitive guide for special folders in windows? An internet search yielded just a few crumbs of information, e.g.
What I'm looking for is an explanation of each folder, its intended purpose, usage scenarios and motivation for its existence (e.g. what does Local App settings provide for that App settings doesn't). A matrix/table of requirements/uses against folder would be handy I think.
How about the CSIDL reference: https://learn.microsoft.com/en-us/windows/win32/shell/csidl
and the KNOWNFOLDERID reference: https://learn.microsoft.com/en-us/windows/win32/shell/knownfolderid
