Nearly a decade ago, this application stood as the heavyweight in Mac compression utilities. Unfortunately, Stuffit Expander (and all related versions) has totally fallen apart over the years. It seems as though each new version becomes riddled with more bugs, bloat, and deviousness than the update before it. I've made it a point over the years to stop supporting developers who only release their applications or files using this compression method. I highly recommend anyone use any other compression type out there.

this is one of the worst apps i've ever seen...
it's very slow, EXTREMELY hard to uninstall and has problems handling rar archieves

Seems bloated.
Opens an extra window each time I open an archive, progress bar is purely fictional. Not a good tool imho

Installed; hated it, uninstalled 5 seconds later. Leaves horrible scars on your machine, had to download an Automator action to wipe it!

Suttfit Expander is useless right now. The Unarchiver works better and faster, plus is open source and reliable. Please, don't use this program so the sitx compression format dissapears forever and for the good of the humanity.

what a piece of crap format sitx is. Avoid it at all costs! sitx must die!

The Unarchiver is WAY better. The only thing it doesn't support is SITX, if you use that a at all. SIT is suppported.

@diggn_it, the installer has an option to run the uninstall.

.sit should die!
