THe guy who is running around claiming false advertising is, I was going to say an idiot, but he's probably smart enough. He made assumptions and then expected the developer to some how "make it happen". He also didn't hear a word of the very patient explanations. His chief complaint is that split archives are not supported by other Mac applications, even though it is a standard format. Which is like saying Microsoft WORD is not a Mac word processor because not every word processor on the Mac can open .doc files.
I have been testing Spriny today and it does everything it says it does and does it quite well. I have a small collection of archiving tools right now and I plan to dump the rest of them and just use Springy. It's fast and has some features that are not available on any other archiving utility on the Mac. Ironically that was basically the malcontents problem, that the developer had the nerve to do some things that nobody else on the Mac was doing yet! How dare he!!!
