Hi Sharon,

That exactly right. CIFS is case-insensitive. When you open camelcase.txt
and there's an existing file CamelCase.txt, the server will return a
handle to that existing file. Then copyTo will *truncate* and write the
new contents. If you really want the name to change you'll need to delete
the existing file first.
