WTH happend to this app

Part of a stuffit suite. Build a zip file and ship it to a Windows user & it has ghost files that all start with "_" as to Unstuffit... been encountering files that won't work after opening a ZIP archive. Then when I go to WinZip and open them, guess what?! They work. C'mon Smith Micro, get your act together.

You had one job!

I hadn’t needed to extract much else than zip files so never needed a utility like this until today where I needed to extract a .rar file someone sent me. I remembered the name Stuffit from back in the day and go figure, they’re still around with a version 16 product. I gave it a try and it fails to do the one thing I downloaded this program for. It said there was something wrong with the .rar file and couldn’t open it. Reading some of the other reviews, I go and download The Unarchiver and guess what? It opens right away with no issues.

Stuffit, you had one job. You’re at version 16! No time for you, the nostalgia isn’t going to cut it. Unistalled.

I tried using this app because I heard about it, so I installed it to try it out. Then, when it got to the last step it didn’t let me even try to do it. How am I supposed to use this when it doesn’t even let me attempt the final step? Do yourself a favor and install actually useful programs like The Unarchiver which I have used for years and the only files it wouldn’t open for me are corrupted files and .exe files because a mac isn’t designed to open .exe files normally. Since it’s freeware I didn’t waste any money, but I sure did waste time downloading and trying it out. Complete junk.
