Thanks, Adam for your quick response.  Given your response regarding the temp files specifically, perhaps I should just reword to ask..  Is there any way to implement restarting the file upload from where it left off, given it may have been interrupted halfway through?  Or is the user "out of luck" and would have to start out all over again.  I'm thinking this a useful feature especially one has queued up a number of large files in a row awaiting upload.  Thanks, Ed.
