SHGetFolderPath() 32 bit vs 64 bit
问题 What happens if I use SHGetFolderPath api call in a 32 bit system with CSIDL_PROGRAM_FILESx86 folder id instead of the CSIDL_PROGRAM_FILES id? Theoretically CSIDL_PROGRAM_FILESx86 should map to C:\program files (x86) in a 64 bit system but what does it map to in a 32 bit system where this path doesn't exist? 回答1: The different scenarios are described in this article on MSDN. Scroll down to remarks, "FOLDERID_ProgramFiles" OS Application KNOWNFOLDERID Default Path CSIDL Equivalent 32 bit 32
