nomarch extracts files from the old `.arc' archive format. It can also
list and test such archives.
(nomarch is primarily intended as a `replacement' for the non-Free `arc'
program.)
Archive::Extract::Libarchive has a similar interface to Archive::Extract, but
instead of using Perl modules and external commands, it uses the libarchive C
libary. It supports many different archive formats and compression algorithms
and is fast.
Mark Adler, maintainer of popular zlib library has released a multicore
capable Parallel Implementation of GZip, nicknamed PIGZ. Version 1.5
implements nearly all of gzip's functionality, including decompression
of .gz and .Z (Unix compress) files.
Python module implementing LZMA Utils' liblzma API
PylibLZMA provides a python interface for the liblzma
library to read and write data that has been compressed
or can be decompressed by Lasse Collin's LZMA Utils.
qpress is a portable file archiver using QuickLZ and designed to utilize fast
storage systems to their max. It's often faster than file copy because the
destination is smaller than the source.
Ruby bindings for Libarchive.
Libarchive is a programming library that can create and read several
different streaming archive formats, including most popular tar
variants, several cpio formats, and both BSD and GNU ar variants.
mkZiplib is a wrapper for Zlib 1.1.3 and Minizip 0.15.
It is free, very portable and works for virtually any computer hardware
and operating system. With mkZiplib you can compress/decompress data and
work with .gz and .zip files from within Tcl.
This is an extract-only program which allows access to the contents of ARJ
archives. You cannot specify a base directory or select individual files
to extract. UNARJ does not support empty directories or volume labels.
Linux ports of KZIP and ZIPMIX by Ken Silverman.
A PKZIP-compatible compressor focusing on space over speed. KZIP
creates smaller .ZIP files than PKZIP with maximum compression
enabled and even beats 7-Zip most of the time.
Zopfli is a new zlib (gzip, deflate) compatible compressor.
This compressor takes more time (~100x slower), but compresses
around 5% better than zlib and better than any other zlib-compatible
compressor we have found.
