You can't determine the size of the file before it has been uploaded,
unless
you're going to install some special software on the client (ActiveX or
Java
components, perhaps) which would do this for you. If you're using a
regular
file upload form, though, there's no way to do this. CFDIRECTORY, like
other
CFML tags, executes on the server, allowing you to manipulate the
filesystem
on the server, not the client.
