        修改文件创建时间、修改时间、大小等属性。
        博客 《C++ 获取文件创建时间、修改时间、大小等属性》分享后，好兄弟“古月”发来一段代码，说可以修改文件的创建时间等。测试了一下真可以，下面是运行效果和代码：

代码

#include <windows.h>
#include <fstream>
#include <iostream>
using namespace std;

int main(int argc, char** argv) 
{
	SYSTEMTIME createTime; //创建时间
	GetSystemTime(&createTime);
	createTime.wDay = 9;
	createTime.wMonth = 02;
	createTime.wYear = 1923;
	createTime.wHour = 1;
	createTime.wMinute = 1;
	createTime.wSecond = 7;

	SYSTEMTIME lastWriteTime; //修改时间
	GetSystemTime(&lastWriteTime);
	lastWriteTime.wDay = 9; 
	lastWriteTime.wMonth = 2;
	lastWriteTime.wYear = 1923; 
	lastWriteTime.wHour = 9; 
	lastWriteTime.wMinute = 37; 
	lastWriteTime.wSecond = 23; 

	SYSTEMTIME lastAccessTime; //访问时间
	GetSystemTime(&lastAccessTime);
	lastAccessTime.wDay = 9; 
	lastAccessTime.wMonth = 2; 
	lastAccessTime.wYear = 1923; 
	lastAccessTime.wHour = 15; 
	lastAccessTime.wMinute = 31;
	lastAccessTime.wSecond = 8; 

	FILETIME lastWriteFiletime;
	SystemTimeToFileTime(&lastWriteTime, &lastWriteFiletime);
	FILETIME createFiletime;
	SystemTimeToFileTime(&createTime, &createFiletime);
	FILETIME lastAccessFileTime;
	SystemTimeToFileTime(&lastAccessTime, &lastAccessFileTime);
	HANDLE filename = CreateFile(L"E:\\LiHai123.txt", FILE_WRITE_ATTRIBUTES, FILE_SHARE_READ | FILE_SHARE_WRITE, NULL, OPEN_EXISTING, FILE_ATTRIBUTE_NORMAL, NULL);
	// 设置文件的时间属性为之前设定的创建时间、最后访问时间和最后修改时间  
	SetFileTime(filename, &createFiletime, &lastAccessFileTime, &lastWriteFiletime);
	CloseHandle(filename);
	return 0;
}
