Updated 16 May 2008 libmpq

P_op	31.42
V_it	1.43

libmpq is a library for manipulating MPQ (MoPaQ) archives, which are used by Blizzard in most of their games (e.g., Diablo, Diablo 2, StarCraft, WarCraft 3, and World of Warcraft). It can extract, move, delete, and create archives.

Updated 10 May 2008 gqviewarc

P_op	19.70
V_it	1.42

gqviewarc is an LD_PRELOAD module that makes GQview treat archives (ZIP, RAR, and maybe more) as directories. It may also be applicable in other domains where transparent stream read access to archived files is needed.

Updated 06 Aug 2012 Lbzip2

P_op	279.17
V_it	13.01

Lbzip2 is a parallel, SMP-based, bzip2-compatible compression utility, with a commandline resembling that of the original bzip2. It is usable both on its own and as a filter passed to GNU tar with the "--use-compress-program" option. It uses Gnulib, and its building and testing process is managed by the GNU build system. Starting with release 2.0, lbzip2 is independent of libbz2 and features yambi, an independent BWT compression stack with improved speed and robustness.

Updated 13 May 2013 Lzip

P_op	528.50
V_it	112.74

Lzip is a lossless data compressor based on the LZMA algorithm, with very safe integrity checking and a user interface similar to the one of gzip or bzip2. Lzip decompresses almost as quickly as gzip and compresses better than bzip2, which makes it well suited for software distribution and data archiving. If you ever need to recover data from a damaged lzip file, try the lziprecover program.

Updated 04 Sep 2008 open-vcdiff

P_op	18.65
V_it	1.00

open-vcdiff contains an encoder and decoder for the format described in RFC 3284: "The VCDIFF Generic Differencing and Compression Data Format." Given a source file and target file, the encoder produces a compact delta file expressing the differences between the two. The decoder reconstructs the target file from the source and delta files. The package includes libraries, headers, and a command-line executable. The chief reason for developers to use open-vcdiff instead of the existing Xdelta package is that open-vcdiff has been released under the Apache license rather than GPL.

Updated 14 Apr 2009 EXIficient

P_op	28.21
V_it	1.85

EXIficient is an implementation of the W3C Efficient XML Interchange (EXI) format specification written in the Java programming language. The EXI format is a very compact representation for the Extensible Markup Language (XML) Information Set that is intended to simultaneously optimize performance and the utilization of computational resources.

Updated 01 Apr 2009 easylzma

P_op	37.88
V_it	1.44

Easylzma is a C library and command line tools for LZMA compression and decompression. It uses Igor Pavlov's reference implementation and SDK. It is meant to be a tiny wrapper and portable build system around a subset of Igor Pavlov's LZMA compression and decompression implementation. The API is small and intended to be straightforward. The project aims to support multiple different prominent LZMA file formats and is focused on producing something that is easy to build and use everywhere.

Updated 04 Dec 2012 At4J

P_op	65.18
V_it	7.49

AT4J is a set of tools for working with data compression and file archives from Java. It supports reading and creating zip and tar files, as well as several types of compression algorithms via third party libraries.

Updated 05 Mar 2012 ImageOptim

P_op	101.34
V_it	4.12

ImageOptim decreases the file size of PNG, JPEG, and GIF images, even those "Saved for Web". It combines OptiPNG, PNGCrush, AdvanceComp, PNGOUT, Jpegoptim + Jpegtran, and Gifsicle for the best possible optimization.

Updated 23 Jan 2013 Lzlib

P_op	190.85
V_it	17.37

The lzlib compression library provides in-memory LZMA compression and decompression functions, including integrity checking of the decompressed data. The compressed data format used by the library is the lzip format.
