AdvanceCOMP is a collection of recompression utilities for your
.ZIP archives
.PNG snapshots
.MNG video clips
.GZ files
The main features are:
* Recompress ZIP, GZ, PNG and MNG files using the Deflate 7-Zip
implementation
* Recompress MNG files using Delta and Move optimization
amigadepacker depacks compressed Amiga formats. PowerPacker, XPK SQSH, MMCMP and
StoneCracker 4.04 (S404) formats are supported. Amigadepacker will automatically
determine the compressed format by content. Among other things, the tool is
useful for playing packed Amiga music formats with uade.
This package creates and extracts-from ARC archives. An ARC archive
contains files which are compressed according to the most efficient
of three algorithms. ARC archives are usually only used for compatibility
with MS-DOS.
This is open source implementation of the world-famous ARJ archiver. This
version has been created with an intent to preserve maximum compatibility
and retain the feature set of the original ARJ archiver as provided by ARJ
Software, Inc.
New ARJ features on Unix-like platforms:
- Support for symbolic and hard links
- Archiving of special entities: pipes and devices
- Support for UID/GID storage in a variety of methods
- World's smallest native self-extracting modules
- Interoperability with ARJ for DOS, Windows, and OS/2 Warp
atool is a script for managing file archives of various types (tar,
tar+gzip, zip, etc.). It provides the following commands:
* aunpack: extract an archive, avoiding tar bombs
* als: list the contents of an archive
* acat: extract files to the standard output
* apack: create an archive
Optional dependencies: lbzip2 or pbzip2, lzip, plzip, lzop, lzma, zip,
unzip, unrar, lha, unace, arj, arc, nomarch, p7zip, unalz.
Bicom is a data compressor in the PPM family. It is freely available and
Open Source. Its most unique characteristic is that compression with
bicom is completely bijective -- any file is a possible bicom output that
can be decompressed, and then recompressed back to its original form. Of
course, any file is also a possible bicom input that can be compressed,
and then decompressed back to its original form. To support encryption
applications, bicom also includes a passphrase-protection option that
will automatically encrypt after compressing, or decrypt before
decompressing.
Brotli is a generic-purpose lossless compression algorithm that compresses data
using a combination of a modern variant of the LZ77 algorithm, Huffman coding
and 2nd order context modeling, with a compression ratio comparable to the best
currently available general-purpose compression methods. It is similar in speed
with deflate but offers more dense compression.
The specification of the Brotli Compressed Data Format is defined in the
following internet draft: http://www.ietf.org/id/draft-alakuijala-brotli
The cabextract is Free Software for extracting Microsoft cabinet files,
also called .CAB files, on UNIX or UNIX-like systems. The cabextract is
distributed under the GPL license. It is based on the portable LGPL libmspack
library. cabextract supports all special features and all compression
formats of Microsoft cabinet files.
This is bzip2, a advanced block-sorting file compressor. It is
believed to be free from any patents.
FREEZE / MELT COMPRESSION PROGRAM
This version is tested under SunOS 4.1.2, Xenix 2.3.2, MS-DOS.
The format of frozen (2.X) file is incompatible with that of frozen (1.0),
but if this package is compiled with -DCOMPAT switch, you will able to
unpack frozen (1.0) files, if you have them.
