Perl-LZO (aka Compress::LZO) provides Perl bindings for the LZO data compression library. You can access the LZO library from your Perl scripts thereby compressing ordinary Perl strings. LZO is a portable lossless data compression library written in ANSI C. It offers pretty fast compression and very fast decompression. Decompression requires no memory. In addition there are slower compression levels achieving a quite competitive compression ratio while still decompressing at this very high speed.

rzip is a compression program for large and very large files. It uses an effective history buffer of 900 MB which allows it to spot redundancy over very long distances. It is usually faster than bzip2 and usually produces smaller files.

Zerotools are a set of tools to aid keeping virtual disks clean by filling binary zero to those regions which are no longer in "use". This is done on-the-fly or manually, depending on which tool suits the needs best. The tools do not compete with other programs that rewrite removed files in order to make their restoration close to impossible. Zerotools are mostly useful for people who compress or archive virtual machines constantly. The tools are run inside the virtualized Linux system and are distribution-agnostic.

UCL is a portable lossless data compression library written in ANSI C. Both the source code and the compressed data format are designed to be portable across platforms. UCL supports in-place decompression. It implements a number of compression algorithms that achieve an excellent compression ratio while allowing very fast decompression. Decompression requires no additional memory.

JAVA LZMA SDK provides developers with documentation, source code, and sample code necessary to write software that uses LZMA compression. LZMA is the default and general compression method of the 7z format in the 7-Zip compression program. LZMA provides a high compression ratio and very fast decompression. LZMA is an improved version of the famous LZ77 compression algorithm. It was improved by increasing the maximum compression ratio, keeping high decompression speed, and low memory requirements for decompressing.

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.

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.

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.
