Hello Jassim,

This could be done in various ways but the most straightforward one is to
have a FileStream [1] instance of your target file, write data to it from
the source and close the Stream when necessary. To resume, open the
FileStream again and seek to the last written byte and continue transferring
data. You can make use of the Position and Length properties or the Seek
method of the FileStream class.

It depends on how you are copying the file.  The shell doesn't provide a
built-in way to do this, AFAIK.  But if you are writing your own copy
code (which is simple enough), it should be a simple matter to look at
the file length of the destination, and use that to determine where to
resume copying.  Just open the destination file for appending, and seek
in the source file to the length of the destination file before you
start reading.
