If you’ve been looking for the ultimate file compression tool, then this offer is for you. Stuffit Deluxe includes Stuffit Archive Manager, Stuffit Scheduler, Stuffit Expander, and StuffIt Destinations™, giving you everything you need to compress and send files.
While I was researching an OS X Tips column for later this week, I came across a .sit file. Now, if you’ve been working with Macs as long as I have (my first Mac was a Performa 638 CD, just before PowerMacs showed up), you’ll know all about .sit files and how to open them.
For those of you new to Macs, especially Mountain Lion, which only seems to handle .zip file archives, you might be a bit stumped as to how to open a .sit file. Well, luckily this old guy is here to tell you how.
