MACRO: MacroBackerUpper—it's like Time Machine for your macro library

Now I understand. Everyone of my backups of all macros as a folder is 560 MB which prompted my question. I have more than 5,000 macros, a testimony to how big a mess they are, not how proficient I am. I will have to sort this out before I install your macro, but frankly, I would not know where to start.
