Open Source Python File Compression Software

LAME is an educational tool to be used for learning about MP3 encoding. The goal of the LAME project is to improve the psycho acoustics, quality and speed of MP3 encoding. Note: we provide source code only!

Crunch is an image compression tool for lossy PNG image file optimization. Using a combination of selective bit depth, color palette reduction and color type, as well as zopfli DEFLATE compression algorithm encoding that employs the pngquant and zopflipng PNG optimization tools, Crunch is effectively able to optimize and compress images with minimal decrease in image quality. While it may produce file size gains larger than those produced by lossless approaches, the impact on image quality is often imperceptible, and optimized file sizes are still significantly lower than the original.

`archivemail' is a tool written in python for archiving and compressing old email in mailboxes. It can move messages that are older that the specified number of days to a mbox-format mailbox compressed with gzip, or optionally just delete old email.

Utility to help create backups more easily. The idea of the program is that all essential information for creating a backup is in a single file. It can use ‘tar’ for creating archives, has a command line interface, and supports incremental backups.

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.

Language-independent interfaces like DOM, SAX and XSLT are not particularly "Pythonic". Several tools are contained in this "XML2Python Interfaces" project that provide more natural ways of translating between XML and Python objects.

Mpyre is a Python front-end to cdparanoia and lame mp3, musepack, ogg vorbis and flac encoders, that includes id3 and apev2 tagging.

This is Python module for RAR archive reading. The interface is made as `zipfile` like as possible.

ebsdiff creates a binary patch file using the bsdiff format. The enhancements to bsdiff are that it stores an MD5 hash of the original file (preventing accidental patching of the wrong file) and can limit the memory it uses while creating the patch file.

LZO is a compression library which is widely used around the world. The main problem with LZO is that it is absolutely not human readable. People have done crazy stuff to get LZO to run in their language. Usually it implies inline assembly or trying to execute data which actually contains machine code. This is sick. Whoever is responsible for this sorry situation ought to be ashamed. So I'm going to deobfuscate LZO and provide a ISC implementation of this algorithm in Python and C. In addition, I will provide a textual description of the algorithm so that it can be easily ported to any programming language. I expect a severe performance degradation, but I leave optimizing for speed to other people.

Grey Compressor+FTP compresses and uploads a single.7z (7-Zip) file to an ftp server. An output .bat file and password .txt file are produced. Send the .bat file and .txt file to the recipient. The recipient then double-clicks the .bat file, and the .7z file is downloaded to the recipient's computer. Pros: * The bat file produced after the file/folder is compressed is the same size each time (easy to send to recipient). * No need to upload compressed file to ftp and send recipient shared url. * Automatic encryption. Cons: * Grey Compressor+FTP may not download .7z file when connected to certain domain networks. * The sender and recipient must have an internet connection. Tips & Tricks: * Rename .bat to .batx if your email service blocks sending your .bat file via email. Recipient then must change the file extension back to .bat. *Grey Compressor+FTP currently has 375 GB of shared server space. This will increase as downloads increase.

rpmdiff is a utility to create a binary patch from one version of an rpm to another. This binary patch can then be distributed to end-users of a distribution who have installed the first version of the rpm and they will be upgraded to the second version.

Tarumba is a desktop independent archive manager that provides fine control for compressed files in a two panel based interface.

Es un compresor de archivos que permite comprimir y descomprimir archivos y carpetas en formato zip. Este ofrece una interfaz con pestañas para facilitar la navegación y el uso de diferentes funcionalidades, como extraer archivos zip y compartir enlaces. Además su objetivo principal es ofrecer una herramienta ligera y eficiente para la gestión de archivos comprimidos.

garchiver is an archiver for Gnome. It has a tree interface that lets you navigate through your archives very easily, as well as the classic WinZip interface. It also has full drag and drop support.

LZHW Command Line Lossless Compression Tool is a Windows command line tool used to compress and decompress files from and to any form, csv, excel etc without any dependencies or installations. Using an optimized algorithm (LZHW) developed from Lempel-Ziv, Huffman and LZ-Welch algorithms. The tool can work in parallel and most of its code is written in Cython, so it is pretty fast. It is based on python lzhw library. Full tool documentation can be found at: https://mnoorfawi.github.io/lzhw/6%20Using%20the%20lzhw%20command%20line%20tool/ While the documentation for the python library is at: https://mnoorfawi.github.io/lzhw/

This tool is featured with a very high compression mechanism hence useful in backing up large sized folders over a slow network, Or useful in reducing the backup size to a maximum possible.

English: Pyrotate is Python program for log files rotation. It uses any external archiver such as Winrar, 7-zip or gzip for compress and may rotate files in GNU/Linux logrotate's style. Program works in any OS such as Windows, Linux, Unix, Mac OS, etc, where Python may work. Dependencies: - Python v2.6 or better v2.7 (v2.5 for pyrotate v0.8 or earlier) - an external archiver Russian: Программа для ротации и/или архивации логов (и любых других) файлов, которая использует любой внешний архиватор и может ротировать файлы в стиле Линуксовой программы logrotate в любой ОС, где работает интерпретатор языка Python. Требования: - Python не ниже v2.6, а лучше v2.7 (или v2.5 для pyrotate v0.8 или ранее) - любой внешний архиватор
