PeaZip 11.3.0

PeaZip is a free archiverfile archiver and file managerfile management tools utility, based on solid and proven Open Source technology of 7-Zip and other great Open Source tools (like FreeARC, PAQ, UPX…) for supporting additional file formats and features, in order to provide an all purpose zip utility featuring a powerful unified GUI that, unlike most of other classic file archivers like i.e. WinZip and WinRar, is natively portable and cross-platformwhat is multi platform software, being available for computers or tablets running 32 bit and 64 bit Windows (9x, NT/2K/XP, Vista/7/8/10, ReactOS, Wine), Linux or BSD x86 and x86-64 (desktop neutral application, supports Gnome, KDE and other desktop environments).

Full (read/write) support

7z, FreeArc’s arc/wrc, sfx (7z and arc), Brotli br, bz2, gz, paq/lpaq/zpaq, pea, quad/balz/bcm, rar (if Rar.exe is available on the system), split, tar, upx, wim, zip / zipx, Zstandard zst

Supporyted encryption standards

7Z: 7-Zip AES256 encryption

ZIP: WinZip AES256 AE, and ZipCrypto for legacy compatibility; can decrypt PKZip’s AES encryption

RAR, if Rar.exe is available in the system: RAR4 EAS128, RAR5 AES256

ARC: FreeARC AES256, Blowfish, Twofish256 and Serpent256

PEA: AES256 EAX authenticated encryption

PeaZip can also be used to try to open any arbitrary file extension with “Open as archive” menu entry, as many file formats are simply variants of archive formats (especially of zip standard).
Even more file structures (forensic file types, WavPack compressed files, etc) can be parsed extending PeaZip capabilities via standard 7-Zip Codecs, copying extra codecs to PeaZip’s folder in res\7z\Codecs path.
In example a large family of codecs (compatible with PeaZip and 7-Zip) is available here7Z codecs – please note TC4Shell codecs are free but closed source, so they can be freely downloaded and installed by end users but they cannot be distributed within PeaZip packages.

PeaZip is localized over than 30 languages and is capable of handling all most popular archive formats (200+ file types), supporting a wide array of advanced file and archive management features (search, bookmarks, thumbnail viewer, find duplicate files and compute hash/checksum value, add, update and edit files inside existing archives, convert archive files…), especially focused on security (strong file encryption, two factor authentication, encrypted password manager, secure file deletion…).
The distinctive trait of PeaZip is the innovative and easy to use compression/extraction interface, more similar to CD burners interfaces rather than to a classic file compressor. This design makes extremely simple to check (and update) items set for compression and extraction, integrating a full featured file manager component.
Also, tasks created in the GUI can be easily saved as batch scripts, in order to automate backup operations, or for fine tuning, or for learning purpose, bridging the gap between the ease of use of GUI applications and power and flexibility of console.

11.3.0
BACKEND
7z/p7zip 26.03
Pea 1.33
Added Test mode for PEA archives
Fixed erroneously reporting some PEA archives as containing relative paths
Fixed “invalid password length” error triggered by some interactive modes
Fixed unchecked size of first compressed block in PEA archives
UNPEA procedure now extracts to a random named temporary work folder first, in case of successful validation the work folder is renamed to actual output name, in case of falied validation it is automatically deleted

CODE
Added instructions to create system-wide Windows hotkeys for PeaZip functions, in (peazip)/res/share/batch/Windows
Improved handling of invalid filenames and interoperability of filenames between different Operating Systems
Updated some app colors to improve blending with supported systems
Various fixes
(Windows) dragdropfilesdll.dll is now loaded at runtime from absolute path, after hash validation
Extended the default list of security-sensitive extensions requiring for user confirmation before being launched, the check is now also applied to “Open/Preview with associated application” other than to doubleclick action
Fixed crash on command line export for compressed tar formats
Fixed crash/hang operating on encrypted ZPAQ archives without providing password in advance
Fixed some keys not working due to incorrect maping into keyboard shortcuts
(Windows) Fixed syntax for checking MoTW and Alternate Data Streams
Improved detection of user’s temp path on non-Windows systems
Improved handling of metacharacters in different stages of the scripting engine (filename validation, command line sanitization)

FILE MANAGER
Added Shift+F12 keyboard shortcut to open the new “Open with” screen, displaying custom applications and common options (open with associated app, custom app, new PeaZip instance); custom apps, scripts, and web services can be defined as usual in Options > Settings > Applications
It is now mandatory to set a master password for the integrated Password Manager
if you are using the Password Manager it is recommended to backup your passwords with previous version of PeaZip (set a master password, rightclick on password list screen and use Export > Encrypted), and import in the new version (use the exported pm file to replace the pm file in PeaZip’s configuration path)
New Blue and Blue-Dark themes, can be set from Option > Themes, Custom
Various usability improvements

EXTRACTION and ARCHIVING
Archive creation screen can now display compression percentage (default) or compression ratio
preference is set from Options > Settings > Archive manager tab, “Archive” group
compression percentage (or compression ratio) is now shown in the second row of the task’s screen
Improved ZPAQ support
ZPAQ format now supports “Force typing password interactively” option
New option to automatically explore output path with PeaZip after task is completed in Options > Settings > Archive manager tab, “After archiving / extraction” group
this option also changes the behavior of internal drag and drop copy/move actions to explore destination path, so they behave consistently with archiving / extraction actions
