PeaZip is an open source file and archive manager: cross platform, available as portable and installable software for 32 and 64 bit Windows and Linux (PeaZip is a desktop neutral application).

PeaZip can extract most of archive formats both from Windows and Unix worlds: currently 134 file extensions are supported 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 suppors a wide range of compression and encryption standard, from fastes 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.

- Additional features:
* split / join files

* compare
* create a file checksums
* performance test systems, etc.

Security
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:
* 7Z's AES256 encryption
* ZIP WinZip's AE encryption based on AES256 (and ZipCrypto for legacy compatibility); can decrypt PKZip's AES encryption
* FreeARC's ARC: AES256, Blowfish, Twofish256 and Serpent256 - this format is also capable to generate recovery records to protect data against corruption
* PEA: AES256 EAX authenticated encryption
