some concepts to improve the way archiving-related tasks are handled,
bridging the gap between GUI and command line based software.
- Save archive layout:
archive layout is
list of object scheduled to be archived or extracted.
When creating a new archive or when extracting existing archives, files
and folders can be added to the archiving or extraction layout which is
visible on the bottom of the first tab of archiving and extraction
interfaces. Layout can be saved (and edited as a text
file), a saved layout can be added to the
current archiving or extraction layout and PeaZip will take care to
verify if entries
are duplicate and if they accessible. Layouts make easier to define,
handle, maintain and edit with external tools the lists of object to be
archived or extracted (i.e., for backup
or restore purpouse).
- Save task definition
as script: most of the tasks possible to do with PeaZip
exported as a command line in a text file, using Save task definition
buttons in Console tab, both
in archiving/conversion and in extraction interface (or button in task's
window). From the console tab the task can be modified and tested.
Advanced users can use those saved scripts (main menu Tools > Saved task definition scripts points
to the default PeaZip's script directory) to speed up
building scripts, or for learning purpose about the underlying
executables, or for fine-tuning the
task bejond the GUI's capabilities.
- Schedule task definition script:
Schedule tab in archive/conversion and extraction interfaces is
intended as a quick way to schedule a task (i.e. to automate backup or
restore) in system's Task scheduler (Microsoft Windows Vista and newer
- Save task log
Each task launched
by PeaZip run in a separate
PeaLauncher instance. If a task ends in error, or test and list tasks,
the task's window is kept open to let the user inspect and the task log
it generated, and the command behind the job.
PeaZip remembers last used compression levels and
for each format; custom options (where applicable), like passes,
dictionary size etc are remembered only for the current session or
until the compression format is changed.
All those settings can be reset to default using the reset button on
Console and graphic
PeaZip can also be set to
always keep open the job's window to always let the user inspect the
job log in Options > Settings > General (1) tab
In the same tab tab
it is possible to set
how those applications are presented to the users (binarie user
interface) chosing between 3 alternative modes:
- Console mode
launch applications with their
console interface, allowing the user to spare resources and to see the
native text-based progress indicator for each application, which
generally is more reliable and detailed than the graphical one.
- Graphic mode
(default) wraps the job in a graphical
presentation making easier to read and save job log and job definition,
to change underlying process priority, to pause or stop the job and to
open the output path in a click. Optionally at job completion the
window can auto close itself or shut down the system. This is the
default mode for most job types.
- Graphic + console
mode allows to get the best
two modes, with a GUI to control the job and a console window to have a
real-time log of ongoing activity.
to stop and undo tasks
You can use "Stop" button in the graphic
stop the underlying
job's process; partial outcome of the task will not be automatically
deleted and will remain available for inspection, as well the job log.
Manage .7Z, .ACE, .ARC,
.BZ2, .CAB, .GZip, .PAQ, .RAR, .TAR, .ZIP, .ZIPX files...
more than 150 file
extensions, only most common ones
are associated by the installer to the application, but all supported
file types can be opened from PeaZip's file browser.
Some file types are minor variations of most common archive formats
(i.e. APK, JAR, PAK and many more variants, and COMPOUND, Microsoft
Office and Open
formats, for structure and supported compression standards, are very
similar to zip archives) and
generally can be opened, even when not explicitly supported by PeaZip,
modifying the file extension.
Anyway, in those cases, additional standards may be mandatory
implemented by the format (i.e. resource's naming conventions,
checksums etc), so if you modify a file opened in that way be sure to
know the specific file format standard.
Hint: a comprehensive online database of file extensions
PeaZip uses Open Source components from 7-Zip/p7zip, FreeArc, and other
state of art Open Source software to offer the same GUI frontend to
browse, test and extract 7z and ZIP archives under Linux and MS Windows
PeaZip for Linux/BSD is desktop-neutral so it can be used either under
Gnome or KDE desktop environment, or also other desktop managers.
System integration mechanisms relies on FreeDesktop standards and
requires a compliant environment, such Gnome and KDE, but basic
archiving operations are not affected.
For most archive formats,
to extract one or
more files you can alternatively:
To enter password in PeaZip
click in the locker icon in the status bar
(in the file/archive browser) or the locker icon below output address
field in extraction (decryption)
and archiving (encryption)
or click Tools > Enter
password / keyfile in main menu, or press F9.
- Use context menu entry "Extract here" or
here (to new folder)"
- Use context menu entry "Extract..." to be asked
output path and other options
- Open the archive in
in PeaZip and use
"Extract" button (you can chose output path, enter password and other
options before confirming with "Ok") to extract selected object, or
Extract > Extract all in application's context menu to extract all
- Open the archive in
and drag desired objects from the application to the system (the
opposite can be used to add objects to the archive)
- Open the archive in
doubleclick on an archived file to preview it
Using a Keyfile is optional,
leave it blank if you don't want to rely on two
factor authentication - use of keyfile increases security over password
only encryption since also having access to the keyfile will be
required to perform the extraction, hampering dictionary and social
engineering attacks for password guessing shortcuts.
PeaZip features an encrypted password
manager (Tools > Password manager from main menu) to securely
manage user's passwords.
PeaZip supports drag and drop?
Drag and drop is
supported on MS Windows systems. You can drag and drop objects from the
system to the
application's icon and in the application's forms (main, archive layout
creation, archive browser).
From 2.1 version, in Windows, PeaZip can drag and drop objects from the
program's forms to the system (either to copy from a folder, or to
unpack fron an archive), through a custom drag&drop function.
It will not show standard Windows drag and drop icons and can drop
items to (file)Explorer windows or desktop.
The advantage of this custom function is that it doesn't need to copy
files to system's temporary path on drag&drop operations, speeding
up a lot the operation if big files are involved (especially noticeable
if files are not in the same volume of system's temp directory) and
don't risking to lowen the security of the operation if the system's
temp folder has security policies different from the ones of the
intended output destination.
PeaZip is yet not integrated with Windows drag and drop's context menu
handler (but it is integrated with rightclick's context menu for
zipping, unzipping and advanced operations).
better than... ?
Being PeaZip a frontend, each time an archive
interprocess communication is involved: if the program / the
input path / the output path is on a slow network or slow unit this may
bring a slowdown.
But most of the time is usually spent on archiving/extracting
operations; in this case PeaZip is as fast as the invoked application
(7z, which is command line 7-Zip
Pea, UPX etc...), which
performance is mainly bound to the algorithm and the compression level
involved, being the underlying executables good and efficient
PeaZip features extremely fast operations, as tar/untar, split/merge
files, create archives with "store" compression level, quite fast
operations (i.e. Deflate based algorithms, like in gzip compression),
operations (when bzip2, LZMA, PPMd,
unrar, unace are involved), up to very slow operations when PAQ at
highest compression levels are used.
A wide range of performances and compression levels can be attained
using PeaZip, the point is in chosing the right balance between the two
Enforcing data security employing cryptography
raises a little the
computing power usage, but on average compter the impact of this factor
is usually negligible; decryption
of protected archives is usually even
faster than encryption.
Learn more in compression
ratio and speed benchmarks of PeaZip
compared with mainstream archive managers.
By default PeaZip prompts to zip / unzip in
path of the
input object, but in archiving and extraction interfaces the Output
group allows to set the output path.
The button on the right of the output address bar opens a standard
output selection dialog, while on the left the button shows a dropdown
menu allowing to select an output path from various pre-sets: system's
paths (inlcuding: current item's path, the last used path, desktop,
documents etc...), paths of bookmarked elements, and recently visited
paths (paths visited in the current session, and paths of previously
created or extracted archives). From this menu It is also possible to
set a default custom output path.
UPX is the only exception from that mechanism since it always compress
the input executable file in place.
In Options > Settings first tab it is available the option "Open
output path when job completes".
Otherwise iin the same tab is available the PeaLauncher options
dropdown menu: select "Always keep open to inspect job report" to be
able, alongside other features, to click "Open output path" button
after the job is completed - otherwise by default the job's window will
auto close if no error is reported.
not responding /
is slow on startup?
PeaZip may be
lengthy operations which needs to wait completion; i.e. PeaZip may be
querying the archive for browsing (especially when flat mode is used on
archives containing many files) or adding / removing files from
archives (needed time depends on the size of the objects and
compression options), or querying the system about files and folders
to be added to archive layout.
Any time a potentially lengthy operation is requested the cursor is
changed to horglass and, when possible, an animation is performed to
inform the user that the operation is running and is needing some time
to be completed.
On startup, PeaZip query the mounted units, so it can be slowed down
if, i.e., the system features remote units over a slow network, or has
defective drives, or slow removable units (like CD/DVD) are being
loaded in the same time.
Another potential source of slowness, both for PeaZip and underlying
backend processes, may be slowed-down disk subsystem, i.e. by high
degree of fragmentation, or cuncurrent disk usage by
antivirus/antimalware (especially if inspecting program's or work
files), p2p, file indexing programs (like Google Desktop, Picasa etc),
updates, paging, etc...
[to run disk-bound speed tests, please take in account that on most
systems files are cached after first usage, so becomes accessible in
less time in following tests]
Some algorithms featured by PeaZip (PAQ, ARC and 7Z at highest level of
compression...) requires big amounts of memory, so it is recommended to
avoid extreme settings which results in the system to page to disk,
that is some orders of magnitude slower than RAM.
Why the progress bar
reached the max, and the job is still running?
The graphic progress bar try to guess the job
progress, but if you need
a real time report of the job's progress the native console
mode is more detailed and accurate.
In Options > Settings first tab, in "Backend binaries interface"
dropdown menu, you can set PeaZip to display both the GUI and
the console window if you want to have both a graphical interface to
control the job and a detailed, real time report on ongoing activities
in the console window.
|Running PeaZip on
PeaZip is integrated to
Microsoft Windows system in the following ways
You can reconfigure
the application's system
integration running the configuration tool in Options > System
(which automatically requires administration rights if needed), or
selecting "Custom installation /
in the installer to access to more options.
- You can rightclick on an object or a group of
and use the PeaZip's entries in context menu or "SendTo" menu to
directly send input
object(s) to a specified PeaZip's function.
- You can drag object(s) on PeaZip's program icon
the program will try to decide how to handle the object(s) provided by
- You can drag objects to an open PeaZip instance
put the application in full control of the process
- You can doubleclick on files of types
PeaZip to open them.
PeaZip run on any full Win32 Microsoft Windows desktop system (or
compatible, as Wine and ReactOS) for any type of personal computer or
tablet (recent releases GUI is designed to be touch-friendly in terms
of clickable area and functions discoverability), so at current level
of development is not known of being possible to run it on Windows
PeaZip is a standalone, almost
self contained zip / unzip application: you can unpack peazip_portable
(.tar.gz) in any path and just click on peazip binary; see
FreeDesktop_integration folder in program's path to know how to
integrate PeaZip with the desktop environment (Gnome, KDE...).
packages for generic Linux or specific
distributions are available as well; on download
pages you can find most up to date package right for your system (RPM,
DEB, TGZ); installable packages automatically integrate PeaZip with the
Distribution-specific packages of PeaZip were also built from Linux
communities, and some I'm aware of are linked on PeaZip for Linux
download page too.
if desired, any 32 bit x86
provided by default (for lack of official x86-64 build) can be
replaced with respective 64 bit counterpart, but please remember that
any 32 bit executable
will need ia32-libs
installed in order to to run on a 64 bit system.
On ARM systems PeaZip can be compiled as ASM parts featured in some
units for performances, can be replaced by pure Pascal alternative
code, see PeaZip for ARM Linux
PeaZip is a cross platform and cross widgetset application, meaning it
can be compiled for different systems and widgetsets.
Precompiled binaries Linux packages are built for GTK2 and Qt, which
modern look and feel and very functional system dialogs.
PeaZip Portable for Linux can be used as alternative to native packages
on BSD systems, due to binary compatibility provided by BSD systems to
PeaZip Portable for BSD contains natively compiled (i386, GTK2) peazip,
pea, pealauncher, and p7zip executables, providing most of the
program's funtions are performed by native binaries, for other
backends, Linux binaries are used.
Many other operating systems and widgetsets are supported by Lazarus,
the IDE used for
PeaZip's development, including GTK1, WindCE, fpGUI and Carbon. If
you want to compile PeaZip from sources see notes for developers
How do I make my
system aware of
PeaZip installable packages authomatically create application's icon,
list PeaZip in available applications and create some KDE ServiceMenu
entries to reach most used program's functions (archive, open, extract
here, extract to new folder).
FreeDesktop_integration folder (featured both in installable and in
standalone versions) contains .desktop files and simple instructions to
add PeaZip to start menus and context menus of desktop environments
following the FreeDesktop standards (like Gnome and KDE), and Nautilus
scripts folder which can be manually copied to user's Nautilus script's
to add PeaZip's functionalities to Gnome's
What if I cannot run
If the system report missing libraries the first time you are running
PeaZip binary, you can generally find missing libraries on your
installation media or, better, if an Internet connection is available,
you can search them online using your installation or update manager,
or even in a web based .rpm or .deb repository; generally missing
libraries are standard, well known and widely available gtk/gkd
components (the most common is libgdk_pixbuf library).
are hardware/software prerequisites?
PeaZip should run on x86-compatible CPU due to some performance
critical sections written in ASM, but pure Pascal replacements exists
for those units, allowing to port PeaZip to other architectures (i.e.
CPU and, mainly, RAM requisites are
bound top the chosen algorithm and compression level, ranging to few KB
for simpler algorithms (like when storing files without compression in
tar/gz/zip formats) to above than a GB for most powerful and complex
algorithms at highest compression level, like LZMA, PPMd and PAQ).
Needless to say, it is the choice of the compression algorithm the most
important factor in determination of job's speed, even if usually the
most advanced algorithms are also the ones which scales better in
performances in multicore enviroments.
As for software prerequisites, all needed software invoked by the
frontend is included in PeaZip packages (being available under suitable
licenses, as open source or royalty free) so no custom package is
needed to be installed to make PeaZip work (with the possible exception
of some standard gtk/gdk related libraries needed to run PeaZip,
PeaLauncher and Pea binaries, which may miss in some system, but are
trustable and widely available).
If you don't want non open source software in your system, like
unrar.so (which brings specific license restrictions about reverse
engineering) or unace binary (closed source, royalty free), you simply
need to delete them from /res/ path in program's folder.
Apple Mac OSX / Darwin
support for Carbon widgetset is alpha (a solution could be
using alternative libraries, as Qt, but I would prefer the native,
default widgetset), and moreover I can rarely have full access to OSX
systems; however the Lazarus support for OSX is quickly progressing,
and my interest in porting PeaZip to OSX platform remains very high.
I hope to be able to deploy PeaZip for OSX in future, and any help and
feedback from users of Lazarus IDE on Apple OSX will be welcome.
For the moment, are available some suggestion about running PeaZip on Apple Mac OSX
emulation / wrapping methods.
