PeaZip
is a free cross-platform file archiver utility that provides an unified
portable GUI for many Open Source technologies like 7-Zip, FreeArc,
PAQ, UPX... free alternative to WinRar, WinZip and
similar
proprietary software.
- Create 7Z, ARC, BR, BZ2, GZ, *PAQ, PEA, QUAD/BALZ, TAR, UPX, WIM, XZ,
ZIP, ZST
files
- Open and extract ACE, ARJ, CAB, DMG, ISO, LHA,
RAR, UDF, ZIPX files and more, over 200 archive types
supported
Features of PeaZip includes: archives
opener and extractor, batch creation and extraction
of multiple
archives at once, convert files, create
self-extracting archives, split and join files,
strong encryption with two factor authentication, encrypted password
manager, secure deletion, find
duplicate files, calculate hash and checksum,
export job definition as script.

What is TAR file format, TGZ
TBZ TXZ files
|
|
TAR is
a popular archiving
format, mainstream for data backup and distribution purpose on Unix and
Unix-like systems, as BSD, Linux and derivates. In use since early Unix
versions, predating integrated archiving and compression formats like
zip and rar, it
was
later standardized by POSIX-1.1988 and POSIX.1-2001. Tar packages are
sometimes referred as "tarballs".
"Tarbomb" refers to a tar
package
purposely built to spam extraction directory with a large number of
files, effect that can be avoided by moders archivers simply employing
"extract to new folder" option.
Maximum size of a TAR
file
Current POSIX.1 2001 revision of the tar standard removed the old
limitation of 8 GB of maximum archive size for tar archives defined in
POSIX.1 1988 standard
TAR
file format doesn't
feature native data compression, so TAR archives are often
compressed
with an external utility like, but not only, GZip, BZip2, XZ (using
7-Zip / p7zip LZMA / LZMA2 compression algorithms), Brotli, Zstandard, and similar
tools to reduce archive's size, i.e. for more compact backup, or
smaller software distribution package.
Resulting compressed files
can be found named with single extension, e.g. TGZ, TBZ, TXZ, TZST, or
with double file extension,
e.g. TAR.GZ, TAR.BR, TAR.BZ2,
TAR.XZ, TAR.ZST.
Adding items to a tarball before compression stage is quivalent to
using solid compression,
which can be beneficial for optimizing output size.
Similarly, TAR also does
not natively support cryptography, but it is possible to compress the
TAR package with a compression format providing file encryption features
such as zip, 7z, arc, pea.

When
it is recommended to use TAR format: it is a good choice for
distributing data on
Linux and
other Unix-like systems, combining it with .gz / .bz2 / .xz / Brotli /
Zstandard compression, in order
to
save bandwidth - if relevant for the intended use. |
|
PeaZip fully support creation and
extraction of TAR files on Windows and Linux systems.

SPEED 
Tar format features extremely fast speed: archiving to TAR file is
equivalent - in speed - of
merging files, faster than raw file
copy as the process avoids overhead of creating a new filesystem
entry for each file. If compression is applied in the pipeline of the
job, it will be likely the speed performance limitating factor.

COMPRESSION
RATIO 
Tar file type is not meant to provide compression, and rely on external
compressors in
pipeline (tar.gz, tar.br, tar.bz, tar.xz, tar.zst) from which depends
the results in
terms of compression ratio.
|
|
ADVANCED
OPTIONS 
Tar standard is meant to provide only archiving of data and metadata.
Other features are
delegated, by specification's design, to external programs pipelined to
Tar command.
