Yea, thought about that too, but I do have some things to take into consideration such as; how often the files are uploaded, can they step on each other (possibly). etc....
So my thought is to have a CI I can upload attachments to and then process the attachment, then remove the attachment once done processing. That way it can have multiple attachments and not step on each other.
Just a thought, but might be the best way to go. I also found a script that process attachments via email also..
