7-Zip

7-Zip is a file archiver and compression utility that specializes in achieving high compression ratios while maintaining broad compatibility with numerous archive formats. It is free and open-source software, distributed primarily under the GNU LGPL license, with certain components under the BSD 3-Clause License or subject to unRAR license restrictions. The software is designed for both personal and professional use on Microsoft Windows platforms, offering native support for 64-bit x64, 32-bit x86, and 64-bit ARM64 architectures. Its core functionality revolves around creating, extracting, and managing compressed archives in its native 7z format, which utilizes the LZMA (Lempel-Ziv-Markov chain-Algorithm) and LZMA2 algorithms. These algorithms enable compression ratios significantly higher than those achieved by traditional formats like ZIP or RAR, particularly for large files or collections of similar data. Beyond its native format, 7-Zip supports reading and writing archives in ZIP, GZIP, BZIP2, TAR, and WIM formats, and it can extract data from a wide range of other formats including RAR, CAB, ISO, ARJ, LZH, CHM, MSI, DEB, RPM, CPIO, XAR, DMG, HFS, NTFS, FAT, VHD, VMDK, UDF, Z, and more. This extensive compatibility makes it a versatile tool for handling nearly any archive encountered in daily computing. The software integrates seamlessly with Windows Explorer through a shell context menu, allowing users to compress files or extract archives directly by right-clicking. It also provides a graphical user interface (GUI) with drag-and-drop support, a two-pane file manager for browsing and previewing archives, and a command-line version (7z.exe and 7za.exe) for scripting and automation purposes.
