Azadi is correct. You cannot do it prior to uploading.

Yet the folks over at ASFusion.com have put together a flash based upload form that you can specify the max file size, and when the user is browsing for the file, anything that doesn't meet the file size limit will not show up as a file.

There may be a few AJAX solutions that you may be able to do something similar, yet I don't know of any off the top of my head.

Keep in mind that CF is a server side solution. CF is not aware of the file size until the file actually reaches the server.

Because of this, as alluded to above, a client side solution such as javascript / flash, etc must be used in combination with CF to accomplish the task.
