UnZip

UnZip will list, test, or extract files from a ZIP archive, commonly found on DOS and Windows systems. A companion program, Zip, creates ZIP archives; both are part of the Info-ZIP project. Both programs are compatible with archives created by PKWARE's PKZIP or Nico Mak's WinZip, but in many cases the program options or default behaviors differ.

pngcrush

pngcrush is an excellent batch-mode compression utility for PNG images. Depending on the application that created the original PNGs, it can improve the file size anywhere from a few percent to 40% or more (completely losslessly). The utility also allows specified PNG chunks (e.g. text comments) to be inserted or deleted, and it can fix incorrect gamma info written by Photoshop 5.0 as well as the erroneous iCCP chunk written by Photoshop 5.5.

Lzlib

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.
The lzip file format is designed for long-term data archiving. It is clean, provides very safe 4-factor integrity checking, and is backed by the recovery capabilities of lziprecover.

FLAC

FLAC is a Free Lossless Audio Codec. The FLAC format supports streaming, seeking, and archival, and gives 25-75% compression on typical CD audio. Input plugins for Winamp and XMMS are also provided.

Lbzip2

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.

gzip

gzip (GNU zip) is a compression utility designed to be a replacement for 'compress'. Its main advantages over compress are much better compression and freedom from patented algorithms. The GNU Project uses it as the standard compression program for its system.

Make CD-ROM Recovery

mkCDrec (Make CD-ROM Recovery) makes a bootable (El Torito) disaster recovery image, including backups of the Linux system to one or more CD-ROM(s) (multi-volume sets). Otherwise, the backups can be stored on another disk, NFS/CIFS disk, or (remote) tape. After a disk crash or system intrusion, the system can be booted from the CD-ROM and one can restore the complete system as it was. It also features disk cloning, which allows one to restore a disk to another disk (the destination disk does not have to be of the same size, as it calculates the partition layout itself). Currently, ext2, ext3, minix, MS-DOS, FAT, VFAT, Reiserfs, XFS, and JFS filesystems are supported. It can restore disks in Software RAID and LVM mode. It supports the One Button Disaster Recovery (OBDR) mode, which simulates a bootable CD-ROM on tape.

Long Range ZIP

LRZIP is a compression program that can achieve very high compression ratios and speed when used with large files using unlimited sized compression windows. It uses the combined compression algorithms of zpaq and lzma for maximum compression, lzo for maximum speed, and the long range redundancy reduction of rzip. It is designed to scale with increases with RAM size, improving compression further. A choice of either size or speed optimizations allows for either better compression than even lzma can provide, or better speed than gzip, but with bzip2 sized compression levels. It also has high grade password protected encryption and full STDIN/STDOUT support.

Dump/Restore

The dump package contains both dump and restore. Dump examines files in a filesystem, determines which ones need to be backed up, and copies those files to a specified disk, tape or other storage medium. The restore command performs the inverse function of dump; it can restore a full backup of a filesystem. Subsequent incremental backups can then be layered on top of the full backup. Single files and directory subtrees may also be restored from full or partial backups.

Speex

Speex is a patent-free compression format designed especially for speech. It is specialized for voice communications at low bit-rates in the 2-45 kbps range. Possible applications include Voice over IP (VoIP), Internet audio streaming, audio books, and archiving of speech data (e.g. voice mail).

FAAC

The FAAC project includes the AAC encoder FAAC and decoder FAAD2. It supports several MPEG-4 object types (LC, Main, LTP, HE AAC, PS) and file formats (ADTS AAC, raw AAC, MP4), multichannel and gapless en/decoding as well as MP4 metadata tags. The codecs are compatible with standard-compliant audio applications using one or more of these profiles.

Plzip

Plzip is a massively parallel (multi-threaded), lossless data compressor based on the lzlib compression library, with a user interface similar to the one of lzip, bzip2, or gzip. It can compress/decompress large files on multiprocessor machines much faster than lzip, at the cost of a slightly-reduced compression ratio. (Note that the number of usable threads is limited by file size). Plzip uses the lzip file format, and the files produced by plzip are fully compatible with lzip-1.4 or newer, and can be rescued with lziprecover.

Clzip

Clzip is a lossless data compressor with a user interface similar to the one of gzip or bzip2. Clzip decompresses almost as fast as gzip and compresses more than bzip2, which makes it well suited for software distribution and data archiving.
Clzip uses the lzip file format; the files produced by clzip are fully compatible with lzip-1.4 or newer, and can be rescued with lziprecover. Clzip is, in fact, a C language implementation of lzip, intended for embedded devices or systems lacking a C++ compiler.
The lzip file format is designed for long-term data archiving and provides very safe integrity checking.
