As a related question, what's the easiest way of writing Perl code without whitespace?

Seriously, what is your reason for wanting to avoid a relatively easy, platform-independent method like File::Copy? If there's really a good reason, and since you seem to be using a Windows network copy, you could just use:

`copy $FileName \\\\somecomputer\\folder\\here\\`;
[download]

or,

system('copy', $FileName, '\\\\somecomputer\\folder\\here\\');
[download]

You need to doubled-up backslashes to avoid escaping issues.
