Panther Unzip is a little utility I wrote to decompress Panther style zip archives under other versions of Mac OS X and keep the resource forks and creator/type codes in tact.

I haven't found a machine running Mac OS X v10.1 to try out this program. There's no reason it shouldn't work and I've confirmed that 10.2 works. It works under 10.3 but that would just be silly.


Mac OS X 10.2 or later

This is probably a great utility, but what can those of us who are running MacOS 7 on 68k Macs use to unzip Panther and other OSX zip files while retaining/restoring the resource fork?

This is a wonderful tool for those of us who use (and need) Stuffit products on our machines. I'm in graphics and am often sent InDesign and Quark 6 files with fonts collected and then zipped using Apple's built-in archiver in OSX. The problem is that once you've installed the Stuffit Deluxe package on your machine, it makes it impossible (apparently) to use Apple's finder de-archiver to open up Zip files and you lose the resource forks in Mac Classic (TrueType and Type 1) fonts, making them utterly useless! Now when I know a zip file is archived on a Mac OSX system, I use this utility and - voila! - all the file types and fonts are preserved again... Thanks so much!!!

I haven't figured out the advantage to using the Panther zip utility except that it's integrated (dropstuff becomes integrated when you register, right?)

I compared file sizes for a few file types between DropZip, DropTar, DropStuff (on a few different sitx settings), and Panther's Zip... and the stuffit utilities all outperformed Apple's built-in "helper"...

Am I missing something?

Fair question. And yes, you are missing something. First of all, Apple's solution is free -- registering StuffIt is not. Second, Apple's archives are cross-platform and can be expanded on nearly every operating system -- StuffIt archives can only be expanded on Mac and Windows systems, and the latter only if a separate Expander application is installed. Finally, StuffIt is simply one more thing to install and potentially muck up your system. With storage and bandwidth as cheap as they are today, saving a few extra kilobytes simply isn't worth the expense and hassle of StuffIt.


Great, thanks for your reply!

Also, the spiffy thing about Panther Unzip is that it keeps the resource fork, while Stuffit Expander destroys it--this proved vitally important for me in a situation where I had to distribute copies of our in-house fonts via a website, so that people at the company where I work could use them with our desktop publishing software, which doesn't exist in an OS X version. This meant that for Mac users, I had to distribute Mac Classic fonts, which consist entirely of resource fork. The only way I could get them onto my website was by using BOMArchiveHelper, otherwise the Unix server they were on would destroy the resource fork, and the only way employees running 10.2 could download the fonts without destroying the fork was via Panther Unzip.
