UNACE Plugin

UNACE Plugin handles browsing and extraction of WinAce's ACE file formatunACE tool and it is needed to open ACE files in PeaZip.
This package is meant to provide free ACE files support as separate plugin since UNACE is released by WinAce as royalty free, but closed source, freeware binaries, unacev2.dll version on Windows systems and corresponding ELF version on Linux systems; UNACE for Linux is a 32 bit executable, so on 64 bit systems it requires ia32-libs to extract ACE files

WARNING: UNACE code is abandoned since 2006, and on Windows platforms unacev2.dll is known suffering critical security issues (e.g. CheckPoint, 2019 02 20).
Out of the box, PeaZip does not come with unacev2.dll (which requires separate manual download and installation from user) so it is immune to said vulnerabilities: UNACE plugin is provided as separate download, so it can be safely installed/uninstalled/removed separately from PeaZip without altering program's functionalities except for ACE files support.
No version of PeaZip will attempt to automatically download or install UNACE plugin, nor will use UNACE plugin (even if installed) to open ace files disguised for other formats
At current state, it is NOT RECOMMENDED to install and use UNACE plugin for Windows, if you have UNACE for Windows package installed it is recommended to uninstall it (or to manually delete unacev2.dll from peazip\res\unace\ directory); in Help > About screen it is featured a button for quick removal of UNACE plugin.
The Windows UNACE packages are here provided for legacy support only, with the recommendation to not work with untrusted ACE archives from untrusted sources; trusted legacy archives should be converted as soon as possible to better supported formats in order to remove dependency from the unmanaged closed source code.

UNRAR / UNRAR5 Plugin (optional, alternative rar extraction engine)

On Windows and Linux systems recent PeaZip versions use by default the 7-Zip / p7zip 15.06 (or more recent) unrar implementation, which is capable of reading (browsing, extracting) RAR5 format natively, so it is no longer needed to separately install this plugin - which it is still provided only as an alternative rar / rar5 files extraction engine.

UNRAR5 Plugin is meant to open RAR files built with most recent RARv5rar5 format standard file format specifications.
RarLab's unrar is royalty-free, and sources are available, but due to unrar licensing restrictionis unrar free software (licensing terms of source code prohibits making a tool that can create RAR-compatible archives) it is widely regarded is unrar free software? is unrar open source software? by Open Source community to not be OSI-compliant - and consequently needs to be deployed as separate add-on for PeaZip project.

Additional Formats Plugin

Additional Formats Plugin v3 contains binaries needed to work with additional formats supported by PeaZip: LPAQ1, LPAQ5, PAQ8F, PAQ8JD, PAQ8L, QUAD and BALZ (browsing and extraction), strip and UPX (executables compression).
Content of this plugin can be simply extracted into PeaZip or PeaZip Portable path, into /res/ folder.
It is also possible to selectively extract only the directories containing binaries to support desired formats.

Windows package contains both 64 bit executables (for most systems) and 32 bit executables (for legacy systems), in separate folders.
Please note that the Windows package contains UPX, which easily triggers false positives from antivirus software on that platform, because while it is technically a safe and legitimate software some Windows malware uses it to compress themselves.

package contains also ARC, LPAQ8, PAQ8O, BCM, and ZPAQ, as those binaries were removed by some packages in order to reduce the dependencies for installation of the base PeaZip application.
Please note this package provides some x86 32 bit executable software, Linux x86 64 bit systems needs ia32-libs to run 32 bit binaries.

The package contains compiled MS Windows binary and sources (Lazarus/FPC).


Various icons, logo, images, wallpapers are available in PeaZip resources directory.


SFX modules are used by 7z and FreeArc backends to create self extracting archives.
To use third parts SFX modules extract and copy the modules into "\res\7z" or "\res\arc" folder (depending if the target of the module is 7z or FreeArc) in PeaZip's path and rename them as existing SFX modules, ie. for 7z use 7z.sfx (conventionally, sfx module with GUI) or 7zCon.sfx (conventionally, sfx module with console interface).
Before that you may want to preserve a copy of original PeaZip's sfx modules copying them into another directory of your choice.

7-Zip compatible SFX modules

Extra SFX modules are available from Igor Pavlov's LZMA SDKsfx repository.
