<h3><big><span style="font-weight: bold;">ZIP
format features and performances</span><br>
</big></h3>
<br>
<span style="font-weight: bold;"><a
name="how_zip_compares_with_7z_rar_formats"></a>ZIP </span>is
a popular <a href="what-is-zip-file.html">compressed file
archiving format</a>, mainstream on Microsoft Windows systems; ZIP file
format
specifications are maintained by PKWare which
originally developed the
format.<br>
<br>
<h4><span style="font-weight: bold;">ZIP
compared to 7Z and RAR formats</span></h4>
Newer archive formats like 7Z and RAR have gained popularity and
introduced several improvements compared to classic zip (but some of
them then were brought into later
ZIP
format revisions): better compression ratio, recovery records to
rebuild accidentally missing data, strong
encryption etc, but ZIP format retained much of its popularity gained
in several years of widespread use, mainly for two factors:<a
href="http://www.7zip.org/"><br>
</a>
<ul>
<li><a
name="advantages_in_using_zip_over_other_formats"></a>ZIP compression
is quite fast and it is
not CPU
intensive (for today's standard) compared to competing standards as rar
and 7z - it's based on Deflate lossless compression algorithm
(like
in GZip format), alternatively Deflate64 or BZip2 based compression is
possible, and supported by PeaZip - that makes ZIP format an ideal
candidate for archiving large quantities of mixed types of data (i.e.
performing a backup), when speed is more important than maximum
compression, which is usually the case with today's large disks and
large, poorly compressible multimedia files.</li>
<li><span
style="background-color: rgb(255, 238, 221);">ZIP support is nearly
ubiquitous</span> (i.e.
most Linux
distributions and Windows since XP have basic support for ZIP standard
out of the box), making ZIP format
the ideal choice when distributing files i.e. downloadable packages,
mail attachments etc.<br>
</li>
</ul>
Recently WinZip (probably the most popular zip file utility on MS
Windows
platform) introduced a new
encryption scheme, Advanced Encryption (AE), AES based; AE-encrypted
archives and classic
ZipCrypto-encrypted archives are supported by PeaZip (for legacy
compatibility purpose, ZipCrypto encryption is weak by today's
standards and should not be used for new files), and it is also
capable to read PKWare's AES encrypted zip archives.<br>
<br>
<span style="font-weight: bold;">Formats based
on ZIP standard</span><br>
Many archive/package formats (i.e. JAR, XPI, APK etc) are based on
modified ZIP standard, and can be consequently read by PeaZip.<br>

<span style="font-weight: bold;"><a

is a new
archiving format implemented in WinZip starting
from
12.1 release, evolved from ZIP specifications with newer data
compression algorithms - BZip, LZMA, PPMd and others.<br>
<br>
<span style="font-weight: bold;">Advantages and
disadvantages of ZIPX format</span><br>
It provides a compression ratio
comparable with RAR format, but ZIPX compression / extraction is
significantly slower than ZIP and marginally slower than RAR, in the
range of operating with 7Z
format.<br>
So, while ZIPX is a more feature-rich and powerful compression format
than ZIP, functionally it
is not an 1:1 replacement of it, being slower and not yet supported by
most third party utilities, an "issue" it shares with most of
ZIP alternative formats.<br>

a pure-archiving format popular on Unix and Unix-like systems</span>
(often
used for backup and for content distribution on those platforms).<br>
<br>
<h4><span style="font-weight: bold;">TAR format
comparison with other archive formats</span></h4>
It does provide only archiving (concatenate input data and metadata in
a single output file), delegating functions as compression, encryption,
parity/integrity check, to external software working in pipeline with
TAR command output - so a direct comparison ot Tar with a compressed
archive format like Rar or Zip is not directly possible,<br>
Tar is often combined with a compression algorithm as <span
style="font-weight: bold;">GZip </span>to save disk space occupation,
originating a compressed tar archive TAR.GZ or TGZ (with zlib's
Deflate).<br>
Combining tar with <span style="font-weight: bold;">BZip2 </span>(TAR.BZ2
or TBZ) allows to attain better compression ratio than Gzip, at expense
of longer / more computing intensive compression and decompression,
anyway BZip2 algorithm performances can be dramatically improved by
multithreading.<br>

style="font-weight: bold;">LZMA </span>compressed tar archives
benefit of compression ratio comparable to 7Z file format, as it is
employed the same LZMA/LZMA2 algorithm discussed in 7Z format paragraph.<br>
Fastest compression / extraction, retaining compression ratio
comparable with Gzip, can be obtained with modern Brotli and Zstandard
compression algorithms, which are explained in detail separately.<br>

<br>
<span style="font-weight: bold;">Brotli and

Both Brotli and Zstandard projects aims to maximum compression and
extraction speed, the main goal being near-real time lossless
decompression of content being distributed over the network, reducing
the latency, transmission time, bandwidth consumption, and compression
/ decompression overhead over traditional lossless compression
algorithms (as zlib's Deflate or Zopfli).<br>
As file archiving formats, at lower compression settings both Brotli BR
format and Zstandard ZST format outperforms for speed fast compressors
like Gzip / ZIP obtaining comparable compression results, and at higher
compression levels are both capable of providing a better than Deflate
compression level, being comparable to BZip2 or even RAR / 7Z formats
compression.<br>
In a direct comparison at current level of development, on modern
multicore CPU Zstandard is
faster than Brotli if multithreading option for its ZSTD binary is
enabled - while provided compression level is quite similar.<br>

<span style="background-color: rgb(255, 238, 221);">Noteworthy
advantage of ARC
format is support for recovery records (like RAR)</span>, for
attempting
data
repair in case of corruption of the archive, and strong encryption with
AES, Serpent and Twofish
(all
up to 256 bit key size) and Blowfish.<br>
Interestingly, ARC
command line syntax is close to WinRAR one, allowing
easy porting of scripts from one program to the other.<br>
PeaZip offers a GUI frontend to create, browse, test, repair and
extract ARC / WRC archives under Windows and Linux (on Gnome, KDE or
other desktop environments).<br>
ARC / WRC files can be currently be browsed only in flat mode (shows
all
objects in archive), but in any other aspect they can be handled as
ZIP / 7Z files (see previous point). <br>
Please note that ARC (or ARK) is also the extension of an archive
format developed by SEA company (not subject of this comparative): it
was of mainstream diffusion before
the introduction of ZIP, and it has
no connection with FreeARC's ARC format. PeaZip does not support SEA

compression is desired regardless speed and memory usage.<br>
<span style="font-weight: bold;">LPAQ </span>is a
"lite"
version of PAQ, meant to be faster but providing lower compression
levels; it is a compression only utility, so LPAQ-compressed files will
feature a double extension, i.e. filename.ext.lpaq. In PeaZip if
multiple files are sent to be compressed by LPAQ they will
be automatically added to a TAR archive before, resulting in the double
extension TAR.LPAQ.<br>
<span style="font-weight: bold;">ZPAQ </span>is the
latest
evolution of the PAQ family, featuring backward
compatibility, while PAQ and LPAQ doesn't, so archives created with a
PAQ/LPAQ version need to be extracted with the same version. PeaZip
offers a GUI frontend to create, browse and extract many PAQ

featuring
high compression ratio and high extraction speed, due to the
observation most types of end users are expected to routinely unpack
data and rarely compress files.<br>
All of those are single file compression formats, so compressed files
will
feature a double extension, i.e. filename.ext.quad.<br>
In PeaZip, if multiple files are sent to be compressed by QUAD, BALZ or
BCM
they will be automatically added to a TAR archive before, resulting in
the double extension TAR.QUAD,TAR.BALZ, TAR.BCM respectively. PeaZip
