Hi,

You need to do your own copying using Streams. For every chunk of data
written to the new file, update a byte counter that you can read when
checking file size.

The article in this link describes how to copy by transferring a byte from
one file to another, although you may want to read and write larger chunks
(multiples of 1024) using Stream.Read/Write.

Wel, you know the length you copied,
why not simply subtract that length?
