Yes, Smith Micro’s venerable
StuffIt 16 (
Mac App Store Link) is still alive and well, and available on the Mac App Store for $10.
The popular app can be used to manipulate ZIP and StuffIt files, which can be browsed as if they were a directory on your hard disk. Of course, you can compress data as well, with the option of encrypting it and adding self-healing features to the resulting archives.
