PeaZip is a file manager and file archiver for Microsoft Windows and Linux.[1] It supports its native PEA archive format (featuring compression, multi volume split and flexible authenticated encryption and integrity check schemes) and other mainstream formats, with special focus on handling open formats.[2][3]
PeaZip is mainly written in Free Pascal, using Lazarus. Released under the terms of the GNU Lesser General Public License, PeaZip is free software.

[edit] Features
The program features an archive browser interface with search and history features for intuitive navigation in archive's content, and allows to apply fine-grained multiple exclusion and inclusion filter rules to the archive; a flat browsing mode is possible as alternative archive browsing method.
PeaZip allows users to run extracting and archiving operations automatically using command-line generated exporting the job defined in the GUI front-end. It can also create, edit and restore an archive's layout for speeding up archiving or backup operation's definition.
Other notable features of the program includes file splitting and joining, secure file deletion, byte-to-byte file comparison, checksum/hash files, system benchmarking, random passwords/keyfiles generation, and integration in the Windows Explorer context menu. In addition, the program's user interface (including icons and color scheme) can be customized.[4][5][6]
PeaZip is available as installable package for Windows and Linux (DEB, RPM and TGZ), and as natively standalone, portable application for both platforms. In the latter form it is available also as PortableApps package (.paf.exe).[7]
Amongst more popular and general-purpose archive formats like 7z, Tar, ZIP etc... PeaZip supports PAQ and LPAQ formats: although usually not recommended for general purpose use (due to high memory usage and low speed) those formats are included for the value as cutting edge compression technology, providing compression ratio amongst the best for most data structures.[8][9]
[edit] Limitations
Currently, users may find some drawbacks in PeaZip. These drawbacks are:
- UTF-8 not fully supported in the GUI.
- The native console's progress indicator for the various utilities is far more reliable than the progress bar displayed by the graphical wrapper.
[edit] Third-party technologies
PeaZip acts as a graphical front-end for numerous third-party open source or royalty-free utilities, including:
- Igor Pavlov's 7z executable and Myspace's POSIX port of 7z under Linux
- Bulat Ziganshin's FreeArc archiver (to not be confused with SEA's ARC)
- PAQ8 and LPAQ executables, maintained by Matt Mahoney and various contributors
- Ilia Muraviev's QUAD
- GNU strip and UPX
- UNACEV2.DLL 2.6.0.0 (royalty-free UNACEV2.DLL license) and UNACE for Linux (royalty-free UNACE for Linux license) (maintained by Marcel Lemke, ACE Compression Software)
Most of these utilities can run both in console mode or through a graphical wrapper that allows more user-friendly handling of output information.
