To uncompress an archive using a standard application, you might need to go through a few steps until you see the output in a new folder. AutoUnpack is really the opposite of other uncompression tools, as you just have to point to a folder after you chose the archive and in a few moments the content is there.
AutoUnpack also benefits of different special tools like the NZB tool. You can decode archives that use this feature but you might need a third party tool in order to accomplish this. Other than that, AutoUnpack is a software that deserves trying it.
