Hi Andy, I'm using remoting/AMF in other parts of my application, so I don't think I'll have a problem sending the data to ColdFusion after it's prepared. I just wasn't sure what to do with the data once I got it to ColdFusion to turn it into a file (I'm fairly new to ColdFusion).
I'll take a look at the ColdFusion toBinary function and I assume that after the data comes out of toBinary I can write the file using cffile. Anyway, it gives me a foothold to get started :-) Thanks!
