HighLnk is a hard-linking tool, which scans the current
directory, searching for files with the same content, then
hard-linking this directory to another location, making two
equal files only point to one real file on the media.

ZZIPlib provides read access on ZIP-archives. The library uses only the patent-free compression-algorithms supported by zlib. Functions are provided that transparently access files being either real files or zipped files, both with the same filepath. The zip-archive can be used in the place of a normal subdirectory. It is written in portable C.

The gzip Recovery Toolkit attempts to automate the recovery of data from corrupted gzip files (including tarballs) through a program called gzrecover. This package is still very experimental at this point.

BitComp is a new compression method using bits repacking.

The LZMA utils package provides Unix utilities implementing LZMA compression from 7zip. It includes lzmash, a compression tool with an interface similar to that of gzip and bzip2. This project has now been superseded by xz.

WebPack is a shell script for automatically packing Web sites by shrinking them without affecting their functionality or appearance.
It is also useful for losslessly shrinking image collections and locating corrupt files. It works by stripping unnecessary information and optimizing the compression of images, and by removing comments/whitespace from HTML, using readily-available tools.

Lhasa is a Free Software replacement for the Unix LHA tool, for decompressing .lzh (LHA/LHarc) and .lzs (LArc) archives. The backend for the tool is a library, so it can be reused for other purposes. Lhasa aims to be compatible with as many types of lzh/lzs archives as possible. It also aims to generate the same output as the (non-free) Unix LHA tool, so it will act as a drop-in free replacement.

dtrx intelligently extracts many different archive
types. It will get the contents from tar, zip,
rpm, deb, and cpio archives, as well as compressed
files, with one simple command. It helps keep your
filesystem sane by putting every archive's
contents into a dedicated directory, and making
sure the owner can read and write whatever's
extracted. It can even recursively extract
archives.

pkt is a universal XML packet archiver. It can manipulate files for
backing up documents, transferring them across networks, emailing them,
and sharing them by other means (p2p etc). It uses plugin filters to
do the job and handles virtually any format available if there is a
plugin for it. It handles encryption, compression, conversion, parity
checking, decryption, decoding, repairing, rebuilding, and other tasks
using a universal file format (XML-based). By default, all pkt output is
in 7-bit ASCII which is UTF encoded and is compatible with XML parsers.
pkt files can be disassembled, reassembled, and repaired by hand if
necessary. pkt also supports the use of 8-bit compressed XML packets for
its archives using one of several compression algorithms. In general,
pkt will try to use the best algorithms available.

Industria is a collection of portable R6RS Scheme libraries for cryptography (AES, DES, Blowfish, HMAC, MD5, SHA-1, SHA-2, RSA, DSA, etc.), zip/gzip/zlib decompression, disassembly of amd64 machine code, Off-The-Record messaging, bytevector pack/unpack syntax, TLS connections via custom binary ports, and more.

GNU Rottlog is a replacement to Red Hat's logrotate. It has similar syntax, but more powerful features to cut and store logs.

NexentaStor is a unified storage solution that installs on standard hardware and provides enterprise class storage at a fraction of the cost of legacy, proprietary storage solutions. NexentaStor is particularly well suited for virtualized environments thanks to the ability of NexentaStor to eliminate duplication of primary data storage, to manage the storage for virtual environments from one interface, and to leverage SSDs to address the random I/O and boot storm issues with virtual environments.
