Because both memory page and volume sector sizes are powers of 2, this memory is also aligned on addresses that are integer multiples of a volume's sector size.FILE_FLAG_SEQUENTIAL_SCAN Indicates that the file is to be accessed sequentially from beginning to end.
This flag also enables more than one operation to be performed simultaneously with the handle(a simultaneous read and write operation, for example).
FILE_FLAG_NO_BUFFERING Instructs the system to open the file with no intermediate buffering or caching.

Extensive research into online dating statistics show that there are some set rules that we all need to follow.
It might not sound very romantic, but you can’t argue with stats and figures and following a set of guidelines will probably help you feel more comfortable when sending your first message.When combined with FILE_FLAG_OVERLAPPED, the flag gives maximum asynchronous performance, because the I/O does not rely on the synchronous operations of the memory manager.However, some I/O operations will take longer, because data is not being held in the cache. File access must be for numbers of bytes that are integer multiples of the volume's sector size.For example, if the sector size is 512 bytes, an application can request reads and writes of 512, 1024, or 2048 bytes, but not of 335, 981, or 7171bytes.One way to align buffers on integer multiples of the volume sector size is to use Virtual Alloc to allocate the buffers, It allocates memory that is aligned on addresses that are integer multiples of the operating system's memory page size.When you specify FILE_FLAG_OVERLAPPED, the file read and write functions must specify an OVERLAPPED structure.
