Free open zip files software for linux

Open Invaders is a fully-GPL interpretation of Taitos Space Invaders. While it is not a perfect clone, the aim of the project is to provide a feature rich clone of the famous arcade game. It features (so far) 14 levels with unique backdrops and a full soundtrack.

Open Partly Copied is a service menu (+ shell-script included) allows by one-click start copying video file from remote storage to local directory and immediately open partially copied file with your default player.

Its necessary if movie plays with delays on direct opening.

After watching movie you may delete copied file by click Yes on dialog box.

Installation instructions:

Its easy. Archieve containts install.sh script. So extract archieve to temp directory and run install.sh

Long Range ZIP is a compression program that can achieve very high compression ratios and speed when used with large files. It uses the combined compression algorithms of 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.
Enhancements:
- Blocks to be compressed by lzma are now scanned by lzo in advance to find incompressible data and bypass attempting to compress them.
- This speeds up substantially attempting to compress incompressible files, and should fix the "lzma getting stuck on an incompressible block" bug.
- Basic Darwin support was added.
- Compression mode was stratified for lower levels of lzma compression.

p7zip is a port of 7za.exe for POSIX systems like Unix (Linux, Solaris, OpenBSD, FreeBSD, Cygwin, ...), MacOS X and BeOS.
7za.exe is the command line version of 7-zip.
7-Zip is a file archiver with highest compression ratio.
Since 4.10, p7zip (like 7-zip) supports little-endian and big-endian machines.
INSTALL:
method 1
- edit install.sh to change DEST_HOME
- ./install.sh : to install
Remark : you must be "root" to install 7za in the directory "/usr/local"
method 2
- 7za is a stand-alone program, you can put this program where you want. example : cp bin/7za /usr/local/bin/7za
- 7z needs its plugins. You must copy the file 7z and the two directories Formats and Codecs in the same destination directory.
- if you want to be able to create SFX archive, copy bin/7zCon.sfx to the directory where 7za or 7z can be found.
Enhancements:
- Bug was fixed: 7-Zip 4.50 beta could not open some .7z archives.
New switch for command line version:
-ssc[-] enables/disables case-sensitive mode for file names.
- Speed optimizations for AES encryption.
- Some bugs were fixed.
- fix built of test_emul
- contrib/gzip-like_CLI_wrapper_for_7z/p7zip now supports commands like :
p7zip -- -name
p7zip "file name"
p7zip file1 file2 file3
p7zip -d file1.7z file2.7z file3.7z

metazip project is an Apache 2.0 module that allows you to serve dynamically-constructed, uncompressed zip files. Thus, your users can choose to download individual files or entire collections, but you dont have to reserve disk space for both.
Main features:
- Extremely efficient, by hooking into Apaches filter system.
- Works equally well for zip, tar, and other archive files.
- Supports resumption of aborted downloads.
- Lightweight, self-contained C implementation.
- Free, open source license (Apache).
Version restrictions:
- Works for uncompressed archives only.
- Requires command line utility to construct .zip.mz "template" file.
- Currently only supported on Linux with GNU bash, gcc, and make.
metazip works by comparing a real, uncompressed archive to the files it contains. It then constructs a special .mz file that contains the "difference" between the files and the archive. This difference contains the metadata that the archive tool uses to extract the files. metazip does not interpret this metadata; it simply records it in the .mz file. After the .mz file has been created, the original archive file can be deleted. Simply place the newly-created .mz file in the same directory as the files it references. The mz command-line utility takes care of most of the details.
When the .mz file is requested, metazip "glues together" the files and the contents of the .mz file to reconstruct the archive file. Because metazip hooks into Apaches filter system, Apache handles all of the heavy lifting. metazip merely creates some high-level data structures.
Therefore, metazips overhead is practically negligible. In addition, Apaches normal functions for resuming aborted downloads, calculating the content length, setting headers, etc. work identically for static files and for metazips dynamically-generated output.
[Note: The only "catch" is that metazip must be prepared to handle its input in arbitrary-sized chunks (called "bucket brigades" in Apache-speak), even though in practice the input will generally be in one large buffer (because its input is the small .mz file). This is reflected in metazips code structure (in metazip.c), but is completely transparent to you.]

Open Tranquera is a repository of reusable components for J2EE application development.

There are UI extensions, Services, and a Persistence layer, integrated with existing open source frameworks.
