Pros & Cons:
An open-source product that many here have suggested is PeaZip, which is easy to use and very versatile. It is capable of extracting from archive types including ACE, ARJ, CAB, DMG, ISO, LHA, RAR, and UDF.
It runs on 32 and 64 bit Windows as well as various Linux distributions. It's open source, portable and a great little program.
PeaZip can extract most of archive formats both from Windows and Unix worlds, ranging from mainstream 7Z, RAR, TAR and ZIP to experimental ones like PAQ/LPAQ family, currently the most powerful compressor available.
For archive creation, PeaZip supports a wide range of compression and encryption standard, from fastest to most powerful ones, and allows to export job definition as scripts to bridge the gap between GUI and console applications, and let the user pick the best of the two worlds.
PeaZip has secure deletion feature, can verify file checksum and hash, and supports multiple strong encryption standards, optionally using two factor authentication (password and keyfile) for increased security.
