PeaZip 11.0.0

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.

CODE

Options > Settings, Browser optimization levels improved and optimized to better fit more user cases, generally improving speed on larger archives, and making performances more uniform for different archive types

Archive folders content calculation step is now better matched with browser optimization level
Archive pre-parsing step (TOC verification) is improved for various cases, up to -87% time if archive TOC is not ordered by name, and up to -94% for very large archives over 100Ks items regardless TOC order
Archive treeview rendering step improved, -30% time, and is now better matched with browser optimization level

Various fixes

Fixed auto ask password for encrypted ARC files
Fixed inconsistencies of icons for Bookmarks, Session history, and Tabs
Fixed preserve archive breadcrumb on forced refresh events
Fixed translation of special folders names in Bookmarks
Prevented starting multiple “auto open tar” events in compressed tar.* archives, unless the archive is closed and re-opened

FILE MANAGER

Added Batch test archives function (Test dropdown menu, File manager group) to test multiple archives without interruption (except for asking for password, if needed) reporting success or failure result in the file manager (CRC column)
Improved File manager

(GTK2) enabled virtual mode by default over 16K items
Improved Bookmarks, it is now possible to add Search and Flat view bookmars of filesystem items (previously working only inside archives)
Improved keeping, and focusing, selection on navigation operations
Internal Drag & Drop > Copy to / Move to does no longer change directory, consistently with internal Drag & Drop > Extract functions
Internal Drag & Drop (extract, copy, move) now supports dropping items to the Breadcrumb bar and to the Tab bar

Minor UI revamp

Added alternative icon rendering styles (Native, Sharp, and Soft) in Style “…” menu, File manager submenu, to improve blending the visual aspect of the app on different widgetsets
Improved fractional scaling and zooming
Updated icons and Themes to work consistently in all widgesets

Task progress window caption now shows global progress percentage when running a batch of multiple archiving or extraction tasks
Updated Password Manager UI, and added function to rate password entropy both in Password Manager and in Password Prompt screens.
