ARC


PeaZip allows to apply powerful multiple search filters to archive's content; create and extract multiple archives at once; create self-extracting archives; export job definition as command line; save archive's layouts; bookmark archives and folders; scan and open with custom applications compressed and uncompressed files etc...


Why PeaZip


Flexibility

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 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.

PeaZip is a reliable solution for most of the archive types you may met,
and will help you in finding the right tool for a wide range of specific needs


Portability

You can use PeaZip on all Windows version and on Linux (PeaZip is a desktop neutral application) with the same features and look and feel; moreover, for both platforms, PeaZip is also available as standalone, portable application not needing installation.

You can bring PeaZip with you and rely on it on multiple platforms


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

PeaZip is focused on security and supports multiple encryption standards


Free as in freedom

PeaZip is freeware, free of charge for any use, and is also free as in freedom since it's Open Source (LGPLv3)

PeaZip contains exclusively Open Source components released under OSI approved licenses


Other features: strong encryption, robust file copy, split/join files (file span), secure data deletion, compare, checksum and hash files, system benchmark, generate random passwords and keyfiles.

PeaZip installable

PeaZip installable, either for Windows and Linux, needs to run with administrative privileges.
The program can be installed once from administrative account and then any user running it will have their own private configuration and bookmark files saved on the user's profile home (Linux) or application data (Windows) folder.
PeaZip's most used functions are reachable from SendTo and context menu (Windows), and from service menus (Linux, KDE) and Nautilus scripts (Linux, Gnome).


PeaZip for Linux 
PeaZip is desktop-neutral so it can be used either under Gnome, KDE or other desktop managers. System integration mechanisms relies on FreeDesktop standards and requires a compliant environment, such Gnome and KDE, but basic archiving operations works on any environment.


You can freely replace backend executables in PeaZip/res directory (any PeaZip release/package) with 64 bit counterpart, if available; please note that on Linux 64 bit systems you will need ia32-libs, as long as you need to run a 32 bit executable.

DEB (i386) packages can be installed on 64 bit Linux using dpkg -i --force-architecture; ia32-libs are required on 64 bit systems
