In "Explorer" works Ctrl+C/Ctrl+V From command line: copy robocopy It is possible to use VinAPI: CopyFile CopyFileEx SHFileOperation RF> (For example, files in the size 70 MB). It not the big file.

Is better to copy the big files breaking it into units (for example on 4). As a rule the big files have low entropy i.e. it makes sense to try to compress the data before transmission.......  torrent it. But the big files now from tens terabyte and above, and 70 it is comparable with the size of a cache of some processors.

Because mechanical disks meet till now, and at them the head between tracks is very slowly rearranged, in comparison with operations of the linear read or write. And ten-other mbytes of storage, it generally about what. _> As a rule the big files have low entropy i.e. it makes sense to try to compress the data before transmission. As a rule, the big files are a cinema. And the cinema rather nasty presses close. Can even grow up a little in the course of tightening.
