求助各位大神，我如何把一个文件夹下的文件移动到另一个文件夹下啊？？？

[code=c]

void CGzDlg::OnOK() 

{

	// TODO: Add extra validation here

	

	//CDialog::OnOK();

	CString yw = "源文件";

	GetDlgItemText(IDC_EDIT1,s_str);

	if(s_str != "")

	{

		str1 += s_str;

		str1 += yw;

	}

	CreateDirectory(str1,NULL);

	SetTimer(1,1000,NULL);

}



void CGzDlg::OnTimer(UINT nIDEvent)

{

	CString str,filename,result;

	GetDlgItemText(IDC_EDIT2,str);

	if(str != "")

	{

		filename += str;

		filename += "*.*";

	}

	switch(nIDEvent)

	{

		case 1:

			WIN32_FIND_DATA FindFileData;

 			HANDLE hFind;

			hFind = FindFirstFile(filename,&FindFileData);

 			if(hFind != INVALID_HANDLE_VALUE)                

 			{

 				while(FindNextFile(hFind,&FindFileData))

				{

					result = FindFileData.cFileName;

			//		SetDlgItemText(IDC_EDIT3,result);

					MoveFile(str,str1) ;//参数为原路径与新路径

//		                        MoveFileEx（str,str1,MOVEFILE_REPLACE_EXISTING);

				}

				FindClose(hFind);

			}

		default:

			break;

	}

	CDialog::OnTimer(nIDEvent);

}
