Given below is the code to delete directory using SHFileOperation

bool DeleteDirectory(LPCTSTR lpszDir, bool noRecycleBin = true)
{
    int len = _tcslen(lpszDir);
    TCHAR* pszFrom = new TCHAR[len+4]; //4 to handle wide char
    //_tcscpy(pszFrom, lpszDir); //todo:remove warning//;//convet wchar to char*
    wcscpy_s (pszFrom, len+2, lpszDir);
    pszFrom[len] = 0;
    pszFrom[len+1] = 0;

    SHFILEOPSTRUCT fileop;
    fileop.hwnd   = NULL;    // no status display
    fileop.wFunc  = FO_DELETE;  // delete operation
    fileop.pFrom  = pszFrom;  // source file name as double null terminated string
    fileop.pTo    = NULL;    // no destination needed
    fileop.fFlags = FOF_NOCONFIRMATION|FOF_SILENT;  // do not prompt the user

    if(!noRecycleBin)
        fileop.fFlags |= FOF_ALLOWUNDO;

    fileop.fAnyOperationsAborted = FALSE;
    fileop.lpszProgressTitle     = NULL;
    fileop.hNameMappings         = NULL;

    int ret = SHFileOperation(&fileop); //SHFileOperation returns zero if successful; otherwise nonzero 
    delete [] pszFrom;  
    return (0 == ret);
}
