Number of days between two filetime structures...

[noods]

I'm basically trying to see if a file is a certain number of days old, so that I can delete it... the code so far looks like:

	FILETIME ft;
	FILETIME ftFile;

	bFinished = FALSE;

	_snprintf(szSearch, sizeof(szPath), "%s\\*.*", szPath);
	hSearch = FindFirstFile(szSearch, &wfd);

	if (hSearch == INVALID_HANDLE_VALUE)
		return FALSE;


	while (!bFinished) {
		if (!(wfd.dwFileAttributes & FILE_ATTRIBUTE_DIRECTORY)) {
			_snprintf(szFileName, sizeof(szFileName),
				"%s\\%s", szPath, wfd.cFileName);


			GetSystemTimeAsFileTime(&ft);
			
			ftFile.dwHighDateTime = wfd.ftLastWriteTime.dwHighDateTime;
			ftFile.dwLowDateTime = wfd.ftLastWriteTime.dwLowDateTime;

			LocalFileTimeToFileTime(&(wfd.ftLastWriteTime));

/*NEED TO COMPARE HERE */


			if (!DeleteFile(szFileName)) {
				;
			}
		}


		if (!FindNextFile(hSearch, &wfd)) {
			if (GetLastError() == ERROR_NO_MORE_FILES) {
				bFinished = TRUE;
			}
			else {
				;
				break;
			}
		}
	}

	if (!FindClose(hSearch)) {
		;
	}


	return TRUE;

This code is not complete I know ... I need to be able to tell how many days old the file is, how do i get this from two FILETIME objects??

One solution is GetFileInformationByHandle().

FILETIME ft1, ft2;
COleDateTime ot1(ft1);
COleDateTime ot2(ft2);
COleDateTimeSpan otspan = ot2-ot1;
otspan.GetTotalDays();
