You need to call CFile::Close before using CArchive::Close

In my opinion the file must be closed after closing the archive

CArchive::Close
void Close( );
throw( CArchiveException, CFileException );

Remarks

Flushes any data remaining in the buffer, closes the archive, and disconnects the archive from the file. No further operations on the archive are permitted. After you close an archive, you can create another archive for the same file or you can close the file. 

The member function Close ensures that all data is transferred from the archive to the file, and it makes the archive unavailable. To complete the transfer from the file to the storage medium, you must first use CFile::Close and then destroy the CFile object.

CFile( int hFile );
[...].The constructor with one argument creates a CFile object that corresponds to an existing operating-system file identified by hFile. No check is made on the access mode or file type. When the CFile object is destroyed, the operating-system file will not be closed. You must close the file yourself.

void CArchive::Close()
{
	ASSERT_VALID(m_pFile);

	Flush();
	m_pFile = NULL; // --> Just detaches the file pointer that's all, but doesn't close
}
