The latest version will not unpack RAR files properly. As soon as you click on any RAR set, it displays an error that one of the files is bad, but hitting continue unpacks Ok (I think). Plus, the app no longer cleans up (deletes) the source files. I would stay with the previous version folks, until someone fixes this!
