W7-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. Since 7-Zip 21.01 alpha, it adds preliminary Linux support in the upstream instead of the p7zip project.

WKGB Archiver is a discontinued file archiver and data compression utility that employs the PAQ6 compression algorithm. Written in Visual C++ by Tomasz Pawlak, KGB Archiver is designed to achieve a very high compression ratio. It has ten levels of compression, from very weak to maximum. However, at higher compression levels, the time required to compress a file increases significantly. As a consequence, the program uses memory and CPU intensively.
WLHA or LZH is a freeware compression utility and associated file format. It was created in 1988 by a doctor Haruyasu Yoshizaki , and originally named LHarc. A complete rewrite of LHarc, tentatively named LHx, was eventually released as LH. It was then renamed to LHA to avoid conflicting with the then-new MS-DOS 5.0 LH command. The original LHA and its Windows port, LHA32, are no longer in development because Yoshizaki is busy at work.
Wpax is an archiving utility available for various operating systems and defined since 1995. Rather than sort out the incompatible options that have crept up between tar and cpio, along with their implementations across various versions of Unix, the IEEE designed a new archive utility that could support various archive formats with useful options from both archivers. The pax command is available on Unix and Unix-like operating systems and on IBM i, Microsoft Windows NT, and Windows 2000.

WThe XAD system is an open-source client-based unarchiving system for the Amiga. This means there is a master library called xadmaster.library which provides an interface between the client and the user application and there are clients handling the special archive formats. Three different types to handle file and disk archives and also disk image files (filesystem) are possible. They can be made by anyone. The master library itself includes some of these clients internally to make the work somewhat easier for the package maintainer and the user installing it.
