Statement on compression performance very similar in January 2002 and April 2017.Type File archiver License LGPLv2.1 with unRAR restriction 9 LZMA SDK in the public domain 10 Website www.7-zip.org.
7Z Zip Uses ItsZip uses its own 7z archive format, but can read and write several other archive formats. The program can be used from a command-line interface as the command p7zip, 11 or through a graphical user interface that also features shell integration. Most of the 7-Zip source code is under the GNU LGPL license; the unRAR code, however, is under the GNU LGPL with an unRAR restriction, which states that developers are not permitted to use the code to reverse-engineer the RAR compression algorithm. As a container format, security or size reduction are achieved using a stacked combination of filters. These can consist of pre-processors, compression algorithms, and encryption filters. Developed by Pavlov, LZMA is a relatively new system, making its debut as part of the 7z format. LZMA uses an LZ-based sliding dictionary of up to 4 GB in size, backed by a range coder. It has had this support since at least version 9.20, which was released in late 2010. Some Microsoft CAB ( LZX compression) and NSIS (LZMA) installer formats can be opened. EXEs ) that are self-extracting archives or otherwise contain archived content (e.g., some setup files) may be opened as archives. The 7-Zip deflate encoder implementation is available separately as part of the AdvanceCOMP suite of tools. The file manager has a toolbar with options to create an archive, extract an archive, test an archive to detect errors, copy, move, and delete files, and open a file properties menu exclusive to 7-Zip. The file manager, by default, displays hidden files because it does not follow Windows Explorer s policies. The tabs show name, modification time, original and compressed sizes, attributes, and comments ( 4DOS descript.ion format). This results in critical drive files and deleted files still existing on the drive to appear. NOTE: Access to the active partition in low-level mode is not allowed for currently when unknown reasons.). Encryption can be enabled for both files and the 7z hierarchy. 7Z Password To SeeWhen the hierarchy is encrypted, users are required to supply a password to see the filenames contained within the archive. WinZip-developed Zip file AES encryption standard is also available in 7-Zip to encrypt ZIP archives with AES 256-bit, but it does not offer filename encryption as in 7z archives. The Windows version comes with its own GUI; however, p7zip uses the GUI of the UnixLinux Archive Manager. A 64-bit version is available, with support for large memory maps, leading to faster compression. On December 2, 2008, the SDK was placed by Igor Pavlov in the public domain. And though the archive dialog has settings that will confound most users, he concluded: 7-Zip fits a nice niche in between the built-in Windows capabilities and the features of the paid products, and it is able to handle a large variety of file formats in the process. In 2007, SourceForge granted it community choice awards for Technical Design and for Best Project. In 2013, 7-Zip received Toms Hardware Elite award due to superiority in speed and compression ratio.
