Every time I download a zip or tar or other compressed file, Stuffit is there to do most of the work for me. And about half of the time I get some annoying error from Stuffit when there doesn’t really seem to be any error. But I use it because it’s what I’ve always used and the creature of habit within demands it.
But I saw the Unarchiver (via CoolOSXApps) the other day, and liked the sound of it. Sure, OS X has the BOMArchiverHelper built-in, but it’s a little restricted in what it’s capable of handling. So having another free alternative to open compressed files is a nice option to have.
What’s your favorite compression/decompression utility? (I like Quicksilver too of course…)
