For Different Hard Disk drive: If the operation is carried between two different hard drives then reading and writing are done with the MultiThreading in parallel.For Same Hard disk drive: But if the copy operation is carried within the same harddisk drive then it is performed using big buffer, reading until the buffer becomes full, and writing in bulk.

It operates lightly because MFC is not used, and it makes it only from Win32 API. The source codes have been opened to the public in the BSD license, you are free modify this software.
