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

HLExtract is a command line utility written in C that can load all HLLib supported packages and extract multiple items from them while maintaining their directory structure. Currently, BSP, GCF, NCF, PAK, SGA, VPK, WAD, XZP, and ZIP (store/deflate) package formats are supported.

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.)

paq is a family of archivers with the best lossless compression ratios now available across a wide variety of test data, according to several benchmarks. A comparison of paq to other compression methods, on a 2GHz T3200, when compressing a large text file: Format Size Time (sec) Memory comp decomp ----------- --------- -------------- ------- Uncompressed 3,152,896 compress 1,319,521 1.6 0.2 .1 MB gzip -9 1,022,810 0.7 0.1 .1 MB bzip2 -9 860,097 0.6 0.4 5 MB p7zip (7z) 824,573 1.5 0.1 195 MB xz -6 822,016 ? ? ? zpaq c1 (fast) 806,959 2 2 38 MB zpaq c2 (mid) 699,191 8 8 112 MB zpaq c3 (max) 644,190 20 20 246 MB The port uses the open ZPAQ specification, and contains: a public-domain C++ API for reading and writing ZPAQ compressed data to or from files or objects in memory; serial and multi-threaded archivers; extra preprocessors for compression; and stubs for creating self-extracting archives.

This package handles LZF de/compression.

Rar is a powerful and effective archiver, which was created by Eugene Roshal and became rather popular quite fast. This extension gives you possibility to read Rar archives.

PEAR::File_Archive is strongly object oriented. It makes it very easy to use, writing simple code, yet the library is very powerful. It lets you easily read or generate tar, gz, tgz, bz2, tbz, zip, ar (or deb) archives to files, memory, mail or standard output. See http://poocl.la-grotte.org for a tutorial.

The PHP_Archive package allows creation of self-contained cross-platform PHP libraries or applications, similar to Java jar files.

Star is the fastest known implementation of a tar archiver. Main advantages over other tar implementations: fifo - Keeps the tape streaming. pattern matcher - For a convenient user interface. sophisticated diff - User tailorable interface for comparing tar archives against file trees. no namelen limitation - Pathnames up to 1024 Bytes may be archived. deals with all 3 times - Stores/restores all 3 times of a file. does not clobber files - More recent copies on disk will not be clobbered from tape. automatic byte swap - star automatically detects swapped archives. automatic format detect - Automatically detects archive formats: old tar, gnu tar, ansi tar, star. fully ansi compatible - star is fully ANSI/Posix 1003.1 compatible.
