Cromfs is a compressed read-only filesystem for Linux. Cromfs is best at archiving gigabytes of big files that have a lot of redundancy. It aims primarily at achieving a strong compression, even at the cost of memory and CPU time resources. It uses the LZMA compression algorithm from 7-zip and block merging.

Versatile Encoder allows you to encode your own videos into good quality DivX files. The input can be a sequence of files (as generated by blender), a single file (if you want to recompress something), or a VCD (if you need to back up a movie). This piece of software tries to guess good defaults and to help the user in making choices.

J7Z is an alternative 7-Zip GUI. 7-Zip is a high-compression file archiver designed by Igor Pavlov. Use J7Z if you want to: update existing archives quickly; backup multiple folders to a storage location; create or extract protected archives; and lessen effort by using archiving profiles and lists.

LRZIP is a compression program and library 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.

PeaZip is a cross-platform file archiver utility that provides a unified portable GUI for many open source technologies like 7-Zip, FreeArc, PAQ, UPX, etc. Creates 7Z, ARC, BZ2, GZ, *PAQ, PEA, QUAD/BALZ, TAR, UPX, WIM, XZ, and ZIP files. It extracts more than 150 archive types: ACE, ARJ, CAB, DMG, ISO, LHA, RAR, UDF, ZIPX, and more. Features of PeaZip include extracting, creating, and converting multiple archives at once, creating self-extracting archives, split/join files, strong encryption with two factor authentication, an encrypted password manager, secure deletion, find duplicate files, calculate hashes, and export job definitions as scripts.

J7Zip handles 7-zip archives. It can lists the contents of the archive, test the archive files, and extract files from the archive to their full paths in the current directory. This version supports only unencrypted archives, and archives with the Copy or LZMA codec.

fuse.gunzip is a filesystem for FUSE that provides transparent decompression of files. The goal is to expedite reading of files by reducing both file size and fragmentation. fuse.gunzip is not a real filesystem such as ext2 or ext3. fuse.gunzip is a virtual proxy filesystem. Compressed files appear as uncompressed when read by the kernel or processes through fuse.gunzip. Any type of file can be compressed.

grzip is a high-performance file compressor based on Burrows-Wheeler Transform, Schindler Transform, Move-To-Front, and Weighted Frequency Counting. It uses the Block-Sorting Lossless Data Compression Algorithm, which has received considerable attention in recent years for both its simplicity and effectiveness. This implementation has a compression rate of 2.234 bps on the Calgary Corpus (14 files) without preprocessing filters. This is essentially an adaptation/extension of GRZipII by Ilya Grebnov.

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.
