It would a bad idea to try and deliver such big files over CF. A file of
that size would take a very long time to download, and the likelihood of the
http connection being lost is very high, which means users will need to keep
trying to download from scratch, as has been stated, http is not really
intended for this.
As I suggested previously you could use FTP which would be a much better
method as downloads can be resumed. You can provide your users with an FTP
link from a webpage, if you need to generate a unique ftp login for each
user then this can be done via CF as well using an FTP server with an API,
such as gene6 FTP or Filezilla.
