VC++6.0复制和删除指定的文件和文件夹

项目中一小段代码

//-------------------------------------------------
//	复制文件
//-------------------------------------------------
void CVideoDemoDlg::Copy_file()
{
TCHAR   path[200];
CString strSrcPath;
CString strDesPath;
//设置要复制的到文件夹路径
strDesPath = "E:\\";
//设置当前工作路径
SetCurrentDirectory("D:\\");

BOOL bWorking = finder.FindFile("*.*");
while (bWorking)
{

strSrcPath = "D:\\";
CString filename= finder.GetFileName();
//得到文件或文件夹名
if(filename==savanewfilename || filename == "." || filename == ".." || filename == "Recycled" || filename == "System Volume Information")
{   //对于文件系统提供的文件不fj
}
else
{
strSrcPath = strSrcPath + filename;
CopyDirectory(strSrcPath,strDesPath);
//复制目录
}
}
}

//-------------------------------------------------
//	供Copy_file()使用
//-------------------------------------------------
void CVideoDemoDlg::CopyDirectory(CString pTo,CString pFrom)

}

以上代码是用于文件复制和删除,但是其特殊性,是由其需求确认,正在写的当前文件不能复制和删除
