It is developed by Igor Pavlov and was first released in 1999.<ref name="7zipHistory" /> 7-Zip has its own [[Archive file|archive format]] called [[7z]] introduced in 2001,<ref name="7z_format">{{cite web|author1=Igor Pavlov|title=7z Format|url=https://web.archive.org/web/20011205060104/http://www.7-zip.org/7z.html|date=2001-12-05}}</ref> but can read and write several others. The program can be used from a Windows [[graphical user interface]] that also features shell integration, or from a [[command-line interface]] as the command <code>7z</code> that offers [[cross-platform]] support (see [[#Versions|versions]] for details). An obsolete port of 7-Zip to [[POSIX]] systems was called <code>p7zip</code>.<ref name="p7ziphome">{{cite web | url =https://sourceforge.net/projects/p7zip/ | title =p7zip Download |date= July 2016 | website =SourceForge | access-date =2024-01-06 }}</ref> Most of the 7-Zip [[source code]] is under the [[GNU Lesser General Public License|LGPL-2.1-or-later]] license; the [[unRAR]] code, however, is under the [[GNU Lesser General Public License|LGPL-2.1-or-later]] license with an "unRAR restriction", which states that developers are not permitted to use the code to [[reverse-engineer]] the [[RAR (file format)|RAR]] compression algorithm.<ref>{{Cite web|url=https://www.7-zip.org/|title=7-Zip|last=Pavlov|first=Igor|website=7-zip.org|access-date=31 October 2012}}</ref><ref>{{Cite web|url=https://www.7-zip.org/license.txt|title=7-Zip β License for use and distribution|last=Pavlov|first=Igor|website=7-zip.org|access-date=31 October 2012}}</ref> Since version 21.01 alpha, Linux support has been added to the 7zip project.<ref name="7zip-linux">{{cite web |url=https://www.phoronix.com/scan.php?page=news_item&px=7-Zip-21.01-Initial-Linux |title=Upstream 7-Zip Adds Preliminary Linux Support |last=Larabel |first=Michael |date=2021-03-12 |publisher=Phoronix |language=en|accessdate=2021-03-17}}</ref>
