FileInfoCopyTo Method (String, CopyOptions)
Returns a new file, or an overwrite of an existing file if copyOptions is not FailIfExists.
Option NoBuffering is recommended for very large file transfers.
Use this method to allow or prevent overwriting of an existing 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.
