PeaZip Giorgio Tani - (Open Source)

PeaZip is a free archiving tool with very intuitive interface, which can not only create archives, but also split, join, correct, delete, and even compare them using checksum / hash. The software works with its own PEA compression format, but supports all other major formats as well like: 7Z, ARC, BZ2, GZ, *PAQ, PEA, QUAD/BALZ, TAR, UPX, ZIP and Repair FreeArc's ARC.

PeaZip has secure deletion feature, it can verify file checksum and hash, and it supports multiple strong encryption standards, optionally using two factor authentication (password and keyfile) for increased security.
