删除非空文件夹议题，我用SHFileOperation函数，但它不放到回收站，回收是可以正常存放垃圾文件的呀？

[cen_jin_long]

	SHFILEOPSTRUCT fs;
	//SecureZeroMemory(&fs, sizeof(fs));//这句去掉后可以删除非空文件夹
	fs.hwnd = NULL;
	fs.wFunc = FO_DELETE ;//如果上边的那句不要了，移动到回收站。但这里写成 FO_DELETE | FOF_ALLOWUNDO; 是直接会直接删除的。怎么回事？
	fs.pFrom = TEXT("C:\\test");
	fs.pTo = NULL;
	fs.lpszProgressTitle = NULL;
	fs.hNameMappings = NULL;
	SHFileOperation(&fs);

//删除文件到回收站中
//pszPath : 待删除的全路径文件名
//bDelete : TRUE 删除，不移到回收站，FALSE:移到回收站
一、 //返回 : TRUE 删除成功 FALSE 删除失败
BOOL CDelFileToRecycleDlg::Recycle(LPCTSTR pszPath, BOOL bDelete/*=FALSE*/)
{
SHFILEOPSTRUCT shDelFile;
memset(&shDelFile,0,sizeof(SHFILEOPSTRUCT));
shDelFile.fFlags |= FOF_SILENT; // don't report progress
shDelFile.fFlags |= FOF_NOERRORUI; // don't report errors
shDelFile.fFlags |= FOF_NOCONFIRMATION; // don't confirm delete
// Copy pathname to double-NULL-terminated string.
//
TCHAR buf[_MAX_PATH + 1]; // allow one more character
_tcscpy(buf, pszPath); // copy caller's pathname
buf[_tcslen(buf)+1]=0; // need two NULLs at end

// Set SHFILEOPSTRUCT params for delete operation
shDelFile.wFunc = FO_DELETE; // REQUIRED: delete operation
shDelFile.pFrom = buf; // REQUIRED: which file(s)
shDelFile.pTo = NULL; // MUST be NULL
if (bDelete)
{ // if delete requested..
shDelFile.fFlags &= ~FOF_ALLOWUNDO; // ..don't use Recycle Bin
}
else
{ // otherwise..
shDelFile.fFlags |= FOF_ALLOWUNDO; // ..send to Recycle Bin
}
return SHFileOperation(&shDelFile); // do it!
}

我的和这个一样的呀，怎么不行呢？
