I actually have a command line option to preserve it or not. By default, it preserves it, but if you make changes to the length of the item (e.g. a different length string) and the padding is the wrong size, it will always be removed automatically. This guarantees that it won't take any space. Oh, and you can always remove it from the XML file and the alignment will still be maintained automatically (padding with zeros). So it's benign even if you don't disable it completely from the command line. If we eventually determine it's not needed, I'll just have the command line option default to OFF. I just wanted to make sure I could do exact comparison testing like I mentioned in post #10.I'd suggest checking if it is garbage or not - if it is then just throw it away. Matching byte for byte isn't important, but you don't want to have to specify useless padding when making changes.
