PeaZip project development change log





PeaZip 7.8.0 introduces interactive extraction option, asking user to skip or overwrite existing files and folders, as alternative to the classic policy-based unattended extraction - which is still available as alternative.
It is now possible to customize file types triggering "Extract everything for", to set global priority for compression / extraction tasks, and to replace archive extension with a custom one.
On Windows systems, is it now supported drag&drop extraction directly to other applications (i.e. 7-Zip or WinRar), and compression / extraction progress is now shown in application's icon.
On Linux, a new Qt5 build is available as portable package.

A total of 211 file extensions can now be managed by PeaZip.

Translations are available in over than 30 languages, any help is welcome to translate PeaZip to new languages and to maintain current localizations up to date, so please consider taking the time to give a look to translations directory for newer language files and for any resource useful for translators.

BACKEND
PEA 0.77

CODE
(Linux) Alternative Qt5 build is now available as portable package
If a setting requires to restart PeaZip (localization, system integration, change work folder) it is told in the hint text for the item
Various fixes and improvements

FILE MANAGER
(Windows) Drag&drop now allows to drag-extract files directly to other applications, previoulsy it was possible to drag-extract to the system only - 2021 03 22 fix for Windows 32 bit version, sources and legacy Windows 32 bit packages were republished and online hash values were updated
Righclicking an element on the breadcrumb it is now possible to use context menu functions on it - e.g. display properties, open the path in system's file explorer, open command prompt here, etc

EXTRACTION and ARCHIVING
Interactive extraction option (checked by default on Windows) enables two-step extraction for all archive types supported through 7z/p7zip: content is extracted to a fresh folder and then moved to actual output destination with standard system's calls.
When interactive extraction is used, all unneeded levels of directory nesting are removed, and conflicts with existing files are prompted interactively to user.
Unchecking the option, it is possible to perform single-step extraction as in previous versions, with policy based directives to resolve naming conflicts without needing user interaction (recommended when creating scripts).
It is now possible to set custom extensions for "Extract everything for" in Options > Settings > Archive manager, Extract group
It is now possible to replace archive extension with a custom extension from archiving screen, Advanced tab
In res/presets/custom directory are provided some pre built compression settings for comic book archive formats which uses the new custom extension feature
Priority for archiving and extraction tasks can now be permanently set from Options > Settings > General, Tasks priority
(Windows 7+) Global progress is shown in application's icon in taskbar

7.7.1
BACKEND 
Pea 0.76
UPX was removed from Windows packages due the amount of false positives triggered in (low quality) security software; it is possible to add UPX support installing Additional Formats Plugin, or downloading and copying the most up to date UPX executable in res\upx subfolder in PeaZip's directory

CODE
Command line -ext2simple and -ext2simplefolder can now accept also empthy output path (extract to archive's path)
-ext2simplefolder as -ext2folder (switch -*folder) apply smart folder policy, while -ext2simple and -ext2here ignores it
Updated web search (Ctrl+Alt+F3)
Updated Windows installers to work with recent versions of InnoSetup (.exe) and MSIWrapper (.msi)
Various fixes
CPUAARCH64 now disable Intel ASM to allow build on ARM64 architectures
fixed adding multiple .enc suffix
fixed various issues with non-English localizations
fixed issue with preview for special file types (bat, exe, html) resulting in extraction instead of preview
improved handling special characters in password for arc, rar, and pea formats
(Linux) improved handling of special characters in filenames
(Linux) fixed issues with smart folder option

EXTRACTION and ARCHIVING
PEA compression and decompression can now be cancelled from the GUI

2021 01 08
7.7.0
BACKEND
(Linux) Can now optionally use system p7zip, if installed, from Options > Settings, General tab
requires p7zip-full (or equivalent package) to be installed in order to have a 7z binary compatible with PeaZip's requirements in terms of syntax and features

CODE
Various fixes

FILE MANAGER
Added shortcut Ctrl+W to close window, consistently with conventional use in WinRar and Windows file explorer
Improved control over temporary work directory, used when the archive is created or edited, during drag and drop extraction (Windows), and content preview
Output: faster as no copy to destination is needed, more secure as no content is unpacked/decrypted outside of the intended destination path
Output, preview in user's temp
User's temp (as conventionally used by most applications): in case of failure for any reason, user's temp folder is the single place to look for orphaned data and can be safely cleaned
None, user's temp if needed: allows exceptions to perform drag and drop extraction and preview using user's temp
None: no exceptions allowed, no temporary work data is saved, this does not allow to perform neither drag and drop extraction nor preview, as archive content can't be transparently unpacked and passed to system's drag & drop handler, nor to the associated application

EXTRACTION and ARCHIVING
Added read support to .appxbundle format

2020 12 15
7.6.0
BACKEND
(Winodws, ReactOS) McMilk codecs in 7z\Codecs path are now automatically checked at PeaZip startup, in order to disable them (moving in 7z\Codecs\bk) on systems not capable to run them (as XP or ReactOS), and re-enable them on other systems; this works for both Portable and installable packages without requiring manual intervention

CODE
Various fixes

FILE MANAGER
(in left navigation panel) Archive treeview is now automaticaly updated accordingly to browsing in file manager area
 This option can be fine tuned in Options > Settings > Archive manager
Various usability improvements
Can now set current path as default archiving or extraction path
Options > Settings > General, Advanced, and Archive manager tabs reorganized
Improved and updated themes, and simplified Theme tab

EXTRACTION and ARCHIVING
Improved handling ZIP files with code pages different than local

Local code page, then UTF-8 for sysmbols outside local code page (default)
Force UTF-8 for non-ASCII characters
Force local code page
Use a custom code page: an arbitrary code page can be entered by user (the host machine needs to support the code page to run the tasks, otherwise tasks can be saved as scripts and run on different machines)
Text encoding entry is now accessible also from application's file browser context menu, and in Archiving and Extraction screens context menus
Within PeaZip file manager it is now possible to use copy/paste shortcuts Ctrl+C (or Ctrl+X) / Ctrl+V to extract items from archives to filesystem
If clipboard is set to keep multiple selection operations at once:
Copy/paste extraction is possible form multiple archives at once
It is also possibile to mix cut/paste and extraction operations
Extraction targets the file system, it is not currently possible i.e. to directly paste compressed items from archive A to archive B

2020 11 13

CODE
Various fixes

FILE MANAGER
Create new folder is now also available for 7Z/p7Zip and RAR supported archive types

added function to replace / remove non-ASCII characters
all quick rename functions (lowercase, replace string, etc...) are now also available when browsing 7Z/p7zip and RAR supported archive types
Updated icons in embedded theme and added icons to distinguish common archive types
Updated Ten theme

EXTRACTION and ARCHIVING
Added "Extract everything for special file types" (to 7Z-supported archive types) to optionally extract the entire archive (or current path) to preview special filetypes which usually needs external data to properly run, in example .html, .bat, and .exe files
From Options > Settings > Archive manager, Extract group is possible to customize "Extract everything for..." behavior
Never use special preview, Ask, Always (default)
Extract entire archive (default) or Extract displayed items only (items in current path, or matching search filters) which can be faster than extracting the entire archive
Archive timestamp preservation directive is now also applied to rename and delete operations (previously only for add / update)
Options > Settings > Archive manager, Extract group: added option to auto close PeaZip after extraction if no browsing actions took place (default off), useful in example if a downloaded file was opened for quick inspection before extraction
Options > Settings > General (Windows): added options for locking or hiding target window during drag and drop operations, by default target window is hidden and locked while the operation is running
Out of the box default compression levels are set to fast for ZIP and 7Z formats
compared to previous ZIP normal default, ZIP fast is over 400% faster providing 2% worse compression ratio, and 7Z fast is 25% faster providing 3% better compression ratio
compared to previous 7Z normal default, 7Z fast is 500% faster providing 5% worse compression ratio
please note compression levels and compression presets works as usual, the new settings are meant only to provide novice users better performance balance for general purpose tasks
Modified existing preset scripts
10 from faster zip to fast zip
12 (Linux) from .tar.zst to .7z using Zstandard compression (which requires single pass)
Test mode always show details about single files in archive

Added options to add recovery records and repair archive, from "Test" dropdown in tool bar and in "More" group in context menu
RAR
(Windows) Improved creation support using Rar.exe, if featured in the system, introduced as prototype in previous release
Other than in WinRar's application path Rar.exe is now searched also in PeaZip's directory, in case user wants to copy the exe here for portability: it is sufficient to copy Rar.exe from WinRar's path to PeaZip or PeaZip Portable application's path, or in said path into res\ folder, or in a subfolder named res\rar or res\unrar: any of those locations is supported
Add to separate archives and Archive to original path options enabled for RAR backend

(RAR5) use BLAKE2 hash instead of CRC checksum
Create self extracting RAR
Solid archive
Recovery records
Save files open for writing
Save NT security information
Save NTFS streams
Set archive time to last modified object
Improved support for more RAR options is planned in future, to allow efficient RAR creation from PeaZip GUI, providing RarLab's WinRar is installed in the system and Rar.exe is available.

please note PeaZip does not implement any autonomus RAR creation feature, which is prohibited by RarLab's licensing for RAR, and only passes parameters to Rar.exe if separately installed by the user from RarLab's packages

BACKEND
PEA 0.70
(Linux) UPX 3.96
Please note: updating UPX in Windows packages triggered false positives from multiple antimalware, consequently the update was removed from Windows packages restoring UPX 3.95.
This is not, in any way, a fault of UPX, which is and remains a legitimate and safe software, but being one of the tools that may be employed by malware to compress binary payload, it is regarded as higly suspicious by most anytivirus, and in the past it triggered several false positives for PeaZip for Windows, almost at each update, taking months to be corrected from antivirus teams - and some of false positives are not yet fixed after years, nor the feedback mails were ever answered.
For the future I'll consider about introducing UPX support as a separate plugin, so it can be stripped from main package, and manually updated by end user, to keep it up to date e.g. in the case security issues surfaces on older UPX versions.
If you want to use last version of UPX on PeaZip for Windows, please replace the executable manually, until same syntax is honored the executable can be freely replaced.

CODE
Various memory management, speed, responsivity and stability optimizations
For archive browsing, fast mode (equivalent to previous versions default mode):
Up to -15% memory usage browsing archives containing large number of files
Up to +35% speed browsing and testing for encryption archives containing large number of files

FILE MANAGER
Added mass rename option to prepend progressive number to filenames
Action is available in Context menu, File manager > Rename > 1, 2, 3...
Items will be numbered following the current sorting order, e.g. name, time/date, size, extension...
Added support for navigation with mouse buttons
Button3 go up
Button4 go forward
Button5 go back
New archive browsing optimization option available in Options > Settings > General, Performance group
Normal, no optimization
Fast (default, works as "fast open routine" option in previos versions), stop pre-browsing archives containing very large number of files to preserve performance
Fastest, do not pre-browse archives for very fast opening, as downside this mode does not show archive information, and may non correctly list some out of standard archives
Row select option for file / archive browser is now duplicated in context menu > Navigation for better discoverability
Updated translations

EXTRACTION and ARCHIVING
Fixed: archives are tested for encryption before extraction from SendTo menu entries and from command line
Improved detection of multipart archives for automatic deletion after extraction option
Alongside .001 spanning (as in 7-Zip and PeaZip) are now recognized .z01, .zx01, .rar01, .part1.rar spanning conventions followed by WinZip and WinRar

FILE MANAGER
Added option to automatically open tar archive inside tar.* compressed files
Option is on by default, can be set in Options > Settings > Archive manager
Drag & drop can now be hot swapped between standard and custom mode while using the application
Improved finding duplicate files, both with crc/hash and quick duplicate check: Info column shows "D" for duplicate for each copy of file with same digest value, except the last copy found
Sorting files for Info column allows to quickly select (and delete) duplicate items
Sorting files for checksum/hash column allows to easily compare identical files as in previous versions
New function to analyze content of folders in file browser (from column header menu)
Info column marks empty folders with "E"
Checksum/hash column shows content of folders: number of directories, number of files, and total size
New scaling mechanism for better support of high DPI in PeaZip and Pea executables
UI elements are scaled at run time at discrete steps zooming up to 10x of design time size, using Lazaruz LCL scaling
Graphic is accordingly scaled at run time, accepting arbitrarily sized graphic sources
Embedded 16 and 32 pixel icons are currently provided with 3x definition (48 and 96 pixel respectively) to provide high quality graphic up to 300% scaling
New themes for PeaZip version 7+ uses 8 or 32 bit PNG with transparency, and currently provides 16 and 32 pixel icons upscaled to 3x definition
New Windows icons for menus and file types; new icons allows to better distinguish supported file types, at large and small resolutions
When a single file of unsupported format is passed as parameter, the application lets the user decide if to try to open it as archive or to add it to new archive
Various fixes
Fixed System benchmark tool

EXTRACTION and ARCHIVING
Improved progress bar accuracy
Option to delete input files after task completion is now globally applied to all archiving / extraction functions
Also batch version of direct archiving / extraction functions now apply the deletion on completion policy accordingly to the application's configuration
Alternative versions of batch commands are now available in order to explicitly ignore deletion on completion policy, with "i" appended after function name: -add2peai, -add2crypti, -add27zi, -add27zmaili, -add2separate7zi, -add2sfx7zi, -add2sfx7zmaili, -add2zipi, -add2zipmaili, -add2separatezipi, and -ext2herei, -ext2folderi, -ext2toi, ext2tofolderi, -ext2simplei, -ext2simplefolderi
Fixed and improved -add2split batch command, can now accept multiple input files and folders (if more than one file is passed as input it will be consolidated in a tar archive)

WINDOWS & LINUX INSTALLERS
Improved Windows 32 and 64 bit installers
