There's no documented function in Windows to do this, as the
concept "append file x to file y". Thus, nothing in .NET to do this.
You'd have to write something that modified the filesystem. In FAT it
would be pretty easy, simply modify the file allocation table for the
first file (replacing the

I appreciate the performance concern and will certainly take that into

Take a look at the FileStream class. It gives you the possibility to
Append to a file. I see how in the short term appending to a file

The overload on the constructor assumes that data is going to be written
into the file which is being opened for Append. I do not want this. I
