文件信息

BOOL GetFileAttributesEx(  LPCTSTR lpFileName,  GET_FILEEX_INFO_LEVELS fInfoLevelId,  LPVOID lpFileInformation);lpFileName:文件名fInfoLevelId: 就传这个GetFileExInfoStandardlpFileInformation: 传入一个WIN32_FILE_ATTRIBUTE_DATA结构的指针。typedef struct _WIN32_FILE_ATTRIBUTE_DATA {     DWORD dwFileAttributes;     FILETIME ftCreationTime;     FILETIME ftLastAccessTime;     FILETIME ftLastWriteTime;     DWORD nFileSizeHigh;  DWORD nFileSizeLow;} WIN32_FILE_ATTRIBUTE_DATA, *LPWIN32_FILE_ATTRIBUTE_DATA;从结构中可以取出创建时间和最后访问时间。是FILETIME类型的：typedef struct _FILETIME {   DWORD dwLowDateTime;   /* low 32 bits  */   DWORD dwHighDateTime;  /* high 32 bits */} FILETIME, *PFILETIME, *LPFILETIME;再调用下面这个函数转换为SYSTEMTIME，年月日时分秒就都出来了：BOOL FileTimeToSystemTime(  const FILETIME* lpFileTime,  LPSYSTEMTIME lpSystemTime);
