Not sure it is the real winzip.

This program has very limited functionality compared to windows version.

1) You can not create multipart files 2) Uncompressing archives over 1 gb takes much much more then twice the time of alternative osx unarchievers. (x10 or x100 maybe x1000 more time as I couldn’t stand and wait canceling the task).

Not recommended to anyone. Use free alternatives for osx. They are lightyears better then this.
