7-Zip is a free and open-source file archiver, a utility used to place groups of files within compressed containers known as "archives". It is developed by Igor Pavlov and was first released in 1999. 7-Zip 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, 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.

Formats
7-Zip is a file archiver with a high compression ratio. Usually, 7-Zip compresses to 7z format 30-70% better than to zip format. High compression ratio in new 7z format with LZMA compression. Supported formats - Packing/unpacking: 7z, ZIP, GZIP, BZIP2, and TAR. Unpacking only: 7z, ZIP, RAR, GZIP, GZ, BZIP2, BZ2, TAR, CAB, ISO, ARJ, LZH, LHA, CHM, MSI, WIM, Z, CPIO, RPM, DEB, CPIO, DMG, FAT, HFS, LZMA, NTFS, SPLIT, SWM, TAZ, TBZ, TBZ2, TGZ, TPZ, VHD, XAR, XZ, Z and NSIS. For ZIP and GZIP formats, 7-Zip provides a compression ratio that is 2-10 % better than the ratio provided by PKZip and WinZip. Self-extracting capability for 7z format. Integration with Windows Shell. Powerful File Manager. Localizations for 70 languages.

File manager

7-Zip comes with a file manager along with the standard archiver 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 (all comments for a directory's files are stored in a text file on that directory called,descript.ion which can be edited offline).

When going up one directory on the root, all drives, removable or internal appear. Going up again shows a list with four options:

  • Computer: loads the drives list
  • Documents: loads user's documents, usually at %UserProfile%\My Documents
  • Network: loads a list of all network clients connected
  • \\.: Same as "Computer" except loads the drives in low-level NTFS access. 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 unknown reasons.)

Features

7-Zip supports:

  • The 256-bit AES cipher. Encryption can be enabled for both files and the 7z hierarchy. When 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.
  • Volumes of dynamically variable sizes, allowing use for backups on removable media such as writable CDs and DVDs
  • Usability as a basic orthodox file manager when used in dual panel mode
  • Multiple-core CPU threading
  • Opening EXE files as archives, allowing the decompression of data from inside many "Setup" or "Installer" or "Extract" type programs without having to launch them
  • Unpacking archives with corrupted filenames, renaming the files as required
  • Create self-extracting single-volume archives
  • Command-line interface
  • Graphical user interface. The Windows version comes with its own GUI; however, p7zip uses the GUI of the Unix/Linux Archive Manager.

7-zip does not provide a way to control the file order inside archives. It ignores file name order in command line. Consequently, 7-zip is not usable in cases where the order of file names is important. For example, the EPUB format, which is based on Zip and HTML formats, requires a certain order of the files in archives: a file named "mimetype" must be the first file in the ZIP archive.

Security

Self-extracting archives (including the executable installer of 7-Zip itself) are vulnerable to arbitrary code execution through DLL hijacking: they load and run a DLL named UXTheme.dll if it is in the same folder as the executable file. 7-Zip 16.03 Release notes say that the installer and SFX modules have added protection against DLL preloading attack.

The versions of 7-Zip prior to 18.05 contain an arbitrary code execution vulnerability in the module for extracting files from RAR archives (CVE-2018-10115), a vulnerability that was fixed on 30 April 2018.

Reception and usage

Snapfiles.com in 2012 rated 7-Zip 4.5 stars out of 5, noting, "[its] interface and additional features are fairly basic, but the compression ratio is outstanding".

On TechRepublic in 2009, Justin James found the detailed settings for Windows File Manager integration were "appreciated" and called the compression-decompression benchmark utility "neat". And though the archiving 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."

Between 2002 and 2016, 7-Zip was downloaded 410 million times from SourceForge alone.

The software has received awards. In 2007, SourceForge.net granted it community choice awards for "Technical Design" and for "Best Project". In 2013, 7-Zip received Tom's Hardware Elite award due to superiority in speed and compression ratio.

7z has an open architecture, so it can support any new compression method, too. The following methods currently are integrated into 7z:
LZMA - Improved and optimized version of the LZ77 algorithm
PPMD - Dmitry Shkarin's PPMdH with small changes
BCJ - Converter for 32-bit x86 executables
BCJ2 - Converter for 32-bit x86 executables
BZip2 - Standard BWT algorithm
Deflate - Standard LZ77-based algorithm

LZMA is the default and general compression method of 7z format. The main features of LZMA are:
High compression ratio
Variable dictionary size (up to 4 GB)
Compression speed: about 1 MB/s on 2 GHz CPU
Decompression speed: about 10-20 MB/s on 2 GHz CPU
The small memory requirement for decompression (depend from dictionary size)
Small code size for decompression: about 5 KB
Supports multi-threading and P4's hyper-threading

What's New:
Encryption strength for 7z archives was increased:
the size of the random initialization vector was increased from 64-bit to 128-bit, and the pseudo-random number generator was improved.
Some bugs were fixed.
