Don’t workinig [attachaway] shortcode

Hi there, first at all thanks. Second, I asume three things that i would like to know to resolve my problem.
first assumption: when you upload a file with [file-up] shortcode from a page/post it is save (on the system “File-Away”) with the post_id or some like this?.
Second assumption: the file can be shown by [attachaway] shortcode on the same page/post that was loaded.
third assumption: those two shortcodes will still be working by calling them from a custom template and php code: echo do_shortcode( ‘[fileaway]’); echo do_shortcode( ‘[fileup]’);
Many thanks again!
