Creating folders in My Documents - c++

Question

I'm having trouble creating a directory structure in the Windows My Documents directory. I use
ExpandEnvironmentStrings(L"%USERPROFILE%\\Documents",dir,MAX_PATH);
to get the directory then I create a new Directory in there
CreateDirectoryW(dir,NULL)
then in there I want to create another directory so in essence i want Documents\foo\bar however when I go to the foo directory via the Library on explorer side bar 'bar' isn't found unless I go to C:\users\xxx\Documents\foo then its there. Also if I go to Libraries\Documents\foo and right click->New->Folder isn't an option.
I was wondering if there is a Security Option to CreateDirectory I'm supposed to use or what I'm doing wrong

If you want to create a directory tree, you can use SHCreateDirectoryEx. The following code works well on my computer.
#include <iostream>
#include <Windows.h>
#include <Shlobj.h>
#include <Shlwapi.h>
int main()
{
char path[MAX_PATH];
if (SUCCEEDED(SHGetFolderPath(NULL, CSIDL_COMMON_DOCUMENTS, NULL, 0, path)))
{
PathAppend(path, "foo\\bar");
if (SHCreateDirectoryEx(NULL, path, NULL) != ERROR_SUCCESS)
{
std::cout << "Error: " << GetLastError();
}
}
else
{
std::cout << "Error: " << GetLastError();
}
}
Notice that this works only on Windows 2000 Professional or higher.
