Even so, looking back in time can be the real issue. The other day, I was working with some very old financial archive files on my Mac. So I dragged the archive to Stuff Expander 12, the latest version I had, and got this error message:Īnnoyed, but not alarmed, I did some investigating. So it appeared that I may have had a file that: sit files and they "unstuffed" just fine. was missing a needed resource fork (from Mac OS 9 and early Mac OS X days).had also been encrypted, maybe by another app.That got me curious about how many StuffIt archives I had accumulated over the years. A search with PathFinder showed that I had 2,882. #WHAT IS STUFFIT EXPANDER UPGRADE#Īnd then, of course, my next thought was, mindful of the Snow Leopard upgrade I just did on some fairly new Macs, "What if a day comes, because of technical developments, that I can no longer open those archives? Will the current version of StuffIt Expander work all the way back to the beginning of StuffIt technology? What tools might I need to keep current? I decided to find out. My next step was to figure out the chronology of the company, Aladdin, and the technology. Recall that Raymond Lau developed StuffIt in 1987 and Aladdin Software was formed to market it. StuffIt quickly became the de facto standard for compressing and archiving files in Mac OS, especially in 1990s when we had relatively limited and expensive disk storage. StuffIt Expander a simple utility to expand archives, was a standard third party add-on for all Macs up until Mac OS X 10.4, Tiger. Its big brother, the full featured StuffIt Deluxe was widely used to create and encrypt archives that could easily be sent via e-mail.Įventually, Aladdin became Allume, and in 2005, Allume was purchased by Smith Micro Software. I contacted Matthew Covington, Senior Director of Product Development at Smith Micro in Watsonville, CA where the StuffIt team is. Not only did he provide some suggestions on what the problem with my archive file was, but also brought me up to date on the StuffIt technology. Recovering Old Knowledge for Data Migrationġ. "The current version of StuffIt Expander, which is StuffIt 2009, is able to open archives created by any prior version of StuffIt. This covers the previous history of StuffIt archives ( i.e. Note that Expander is able to open a whole slew of other file formats in addition to the ones that we’ve created - for example the Expander can open zip archives, including encrypted zip archives and zip archives created with newer extensions to the Zip format that WinZip and others have created in recent years that the Finder cannot." sit file format) as well as the newer generation of StuffIt X archives (.sitx file format). In summary, the current StuffIt Expander should be all you'll ever need to open any StuffIt archive ever created. StuffIt Expander 2009 can be downloaded from Smith Micro, free. If neither StuffIt 12 or StuffIt 2009 can open the archives, then the problem is most likely with the file itself." #WHAT IS STUFFIT EXPANDER UPDATE#ĭoes the error result from a bug in StuffIt, or does the error result from some kind of corruption to the archive file itself? The bug in Expander hypothesis can easily be tested - I’d recommend that you download the free Expander 2009 update and see if that has any better luck on your files. I replaced StuffIt 12 with StuffIt 2009, but the archive still wouldn't open.
