Hi Roger,

Outside of checking the cgi.content_length for the size of the file
(which isn't completely secure because users can spoof that if they
want and doesn't help if you're uploading multiple files in the same
form), there is no way to get that information. It would require that
you have access to your users local system, which you never will
unless you're in an intranet environment.

the entire point of that thread was that there was not a way in CF to do
that.

Subject: Check filesize BEFORE uploading


Hi,

I read a mail regarding the subject which said :

"ColdFusion has no way of knowing what the file size is BEFORE it reaches
the
server. The way i've done it is allow the full file to be uploaded, check
the file size (CFFILE) and then delete it. Of course, the system will warn
the user that the file they uploaded was too big AFTER CF has checked it.

It's not a pretty solution, but it's the only one that semi-accomplishes the
task."

So, is there any way that we can check the filesize BEFORE the file is being
uploaded?

Please advice, thanks!

Roger
