CFileFind doesn't find System Directory !!!

This quite short code returns false with GetlastErorr = 18 (no more file). I don't understand what I'm doing wrong.

CFileFind            theFileFinder;
BOOL            result1, result2;

result1 = theFileFinder.FindFile("C:\\WINNT\\system32");
if (result1)
   result2 = theFileFinder.FindNextFile();

>>> My goal is to call GetCreationTime after this to get the system directory creation date (of course I won't use the constant string but I'll use "GetSystemDirectory").

Thanks for any hint.

You did nothing wrong!
FindNextFile finds the next file from A PREVIOUS call to
FindFile. You have only ONE directory which is called "C:\\WINNT\\system32",
so FindNextFile must return false because no more directorys with this name exist!
If you write FindFile("*.*") then FindNextFile will return true because there are more files than match "*.*".

That's maybe correct but a call to GetCreationTime fails if I don't call FindNextFile (as stated in the doc.).

Does that mean it is not possible to access a file directly but that I need to find the "previous" file first and then use "FindNextFile" to get the one I need. That's quite ridiculous to me.

So I found another way. I use the Win32 function "FindFIrstFile" and it works much better than the MFC object.

Thank you for your time.

Ok,
I see thats really confusing ...
Another way is to use GetFileAttributesEx:
WIN32_FILE_ATTRIBUTE_DATA g;
GET_FILEEX_INFO_LEVELS h;
GetFileAttributesEx("C:\\winnt\\system32", h, (void*)&g);

or GetFileInformationByHandle:
BY_HANDLE_FILE_INFORMATION info;
HANDLE hFile = CreateFile ( ("C:\\winnt\\system32",
            GENERIC_READ,
            0,
            NULL,
            OPEN_EXISTING,
            FILE_ATTRIBUTE_SYSTEM,
            NULL );
GetFileInformationByHandle( hFile, &info );
