Depending on the file, if you're downloading something to display specifically such as text, sure, otherwise if you need to pass it to an app such as zip files, word docs etc, you cant, the best you can do is temp files..

Did I just hear "You gotta help us, Doc. We've tried nothin' and we're all out of ideas" ? Is this you? Dont let this be you! I will put in as much effort as you seem to.
