Remarks

Option NoBuffering is recommended for very large file transfers.

The attributes of the original file are retained in the copied file.

Whenever possible, avoid using short file names (such as XXXXXX~1.XXX) with this method.

If two files have equivalent short file names then this method may fail and raise an exception and/or result in undesirable behavior.
