Open Source Windows File Compression Software - Page 2

Abbrevia is a compression toolkit for Delphi, C++Builder, Kylix, and Free Pascal. It supports compressing and decompressing PKZIP, Microsoft CAB, tar, gzip, and bzip2 archives, and can create self-extracting executables. On Windows it also provides Delphi wrappers for the LZMA, Bzip2, and WavPack SDKs, and PPMd decompression. Abbrevia also has several visual controls that simplify displaying and manipulating archives, including treeview and listview components.

Zip-Ada is a library for .zip archives. Full sources are in Ada and are unconditionally portable. Input and output can be any stream (file, buffer,...) for archive creation as well as data extraction. Task safe and endian-neutral. More information on: http://unzip-ada.sf.net Alire crate: https://alire.ada.dev/crates/zipada Mirror: https://github.com/zertovitch/zip-ada/

It supports files and folders multi-compression (UPX, ZIP, 7Z) and archives extraction (several formats). It includes an intelligent UPX compression mode, self-extracting archive creation, encryption/decryption, external compressors and much more.

J7Z is an alternative 7-Zip GUI. It was designed by Xavion. 7-Zip is a high-compression file archiver. It was 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 * Lessen effort by using archiving profiles and lists

A portable version of the ARJ archiver, available for a growing number of DOS-like and UNIX-like platforms on a variety of architectures.

Snappy is a compression/decompression library. It does not aim for maximum compression, or compatibility with any other compression library; instead, it aims for very high speeds and reasonable compression. For instance, compared to the fastest mode of zlib, Snappy is an order of magnitude faster for most inputs, but the resulting compressed files are anywhere from 20% to 100% bigger. Snappy is intended to be fast. On a single core of a Core i7 processor in 64-bit mode, it compresses at about 250 MB/sec or more and decompresses at about 500 MB/sec or more. (These numbers are for the slowest inputs in our benchmark suite; others are much faster.) In our tests, Snappy usually is faster than algorithms in the same class (e.g. LZO, LZF, QuickLZ, etc.) while achieving comparable compression ratios.

UglifyJS is a JavaScript compressor/minifier written in JavaScript. It also contains tools that allow one to automate working with JavaScript code. A parser which produces an abstract syntax tree (AST) from JavaScript code. A code generator which outputs JavaScript code from an AST, also providing the option to get a source map. A compressor (optimizer). it uses the transformer API to optimize an AST into a smaller one. A mangler, reduce names of local variables to (usually) single-letters. A scope analyzer, which is a tool that augments the AST with information about where variables are defined/referenced etc. A tree walker, a simple API allowing you to do something on every node in the AST. A tree transformer, another API intended to transform the tree. All the above utilities and APIs are defined in ~6500 lines of code (except for the effective generation of the source-map, which is handled by the source-map module). Compared to alternatives, UglifyJS is pretty small.

Simplebackup is a cross-platform backup program. It reads a configuration file then builds a compress backup set, finally places the compressed files into another location (a directory, a remote http,ftp,sftp server or even one or more email accounts).

The littleutils include duplicate file finders (repeats, repeats.pl, repeats.py), image optimizers (opt-jpg, opt-png, opt-gif, recomp-jpg), file rename tools (lowercase, uppercase, pren), archive recompressors (to-gzip, to-bzip2, to-bzip3, to-7zip, to-lzma, to-lzip, to-xz), a tempfile utility (tempname), file property tools (filedate, filemode, filenode, fileown, filesize, and lrealpath), and others. See the README file for more details.

AZip is a free Zip Archive Manager with unique features such as: built-in content Search, smart archive Update, archive Recompression. The goal is to keep the user interface as simple as possible and bother the user the least possible with options or useless gadgets.

Moved to GitHub.com/gdraheim/zziplib/ The ZZIPlib provides read access on ZIP-archives. The library uses only the patent-free compression-algorithms supported by Zlib. It provides functions that transparently access files being either real files or zipped files, both with the same filepath

MicroZip is a powerful file compression and encryption utility for mobile phones which allows you to create and extract compressed archives in multiple formats and encrypt sensitive information with powerful AES-256 encryption. MicroZip can create and extract ZIP,TAR,TGZ,TBZ2 archives and extract many other formats as JAR,GZ,BZ2,TBZ,WAR,BZIP2,GZIP,Z,TAZ,CBZ etc. MicroZip allows you to extract selected files without extracting the whole ZIP archive. MicroZip also supports encrypted ZIP archives with both classic ZIP encryption and AES 256 encryption algorithm.

ARC is used to create and maintain file archives. An archive is a group of files collected together into one file in such a way that the individual files may be recovered intact. This repo is obsolete. Use github.com/hyc/arc instead.
