Correction
With regard to ZipStar, before I get myself in hot water, this archiver is not freeware. To
quote from their web page:

"ZipStar may be used free of charge if you

- are a student, teacher or some other kind of member of a teaching facility
(public/private school or university);
- use the software exclusively for private and non-profit purposes.

Self-extracting archives created with ZipStar may be used for private purposes only.
ZipStar is not freeware -- this means that online service providers and similar entities
may only offer ZipStar for download on their pages with an explicit written permission from
SpeedProject"

It wouldn't do to promote the illegal, unlawful and darn right unethical use of software, would it now?
